Cisco Firewall :: Netgear FVX538 - Multiple Subnets On SA520
Jan 5, 2012
I am new to Cisco products. We have currently got a Netgear FVX538 running in front of a few servers. We currently have 2 ranges of IP addresses provided to us on 2 separate subnets. We configured the netgear box with the first IP addresses of each subnet as the IP address of each of the primary and secondary LANs. This then allowed us to set the gateway addresses of servers on the network to either of those 2 addresses, depending on it's range.
This all worked fine - except for the fact that the Netgear box is incredibly flakey, so we decided to get a Cisco box.
We have gone for the SA520, which I have been trying to configure this afternoon. Unfortunately I am now having concerns as to whether it is possible to configure 2 separate subnets internally on this box in the same way we have done with the netgear box. ie - classical routing, one incoming WAN interface with multiple subnets?
I have a Netgear ProSafe VPN Firewall FVX538. But I also have 10 Public IP Addresses that I will like to setup for three web services. So how do I set this up. With multiple routers. Or can my Netgear FVX538 take multiple Public IP Addresses to the same ports. If not how can setup multiple routers. one being the main one.
I have an ASA5510 that is connected to outside for WAN, inside for LAN (10.22.254.0/24), and a iSCSI switch plugged into Ethernet 0/3 (10.22.244.0/24). I can ping the Eth0/3 interface (10.22.244.1) but I can't ping across that interface from WAN or LAN side.
START CONFIGURATION ASA Version 9.1(1) ! hostname ASA5510
NAT command on 8.4? I am trying to PAT multipule Inside subnets to an IP address. With the example I found I can only PAT one subnet. If I do it the way I have below, it will end up with the last subnet (3.3.3.0) stay in the config. What is the best way of doing it? I have about 20 inside subnets I need to PAT.
I have an existing pair of PIX 515E that has two interfaces. One connected to the public internet via my ISP and one internal. I recently ran out of IP's and had the ISP route an additional block to public IP of my firewall. This isn't working for some reason and I'm trying to figure out why.
The "ip address outside XXX" command defines the outside address and I don't see any way to add a secondary sub net.
I tried just adding a rule to the firewall for one of the IP's in the new subnet, but I can't seem to get traffic to pass though the device.
I have an ASA which is managing internet access from mutiple VLANs configured on a 3560 switch. I want to be able to limit the 100MB internet connection on the ASA on a per subnet (VLAN) basis for the multiple subnets configured on the switch..
so for example
VLAN10 - 10.0.10.0 - limit to 5MB VLAN20 - 10.0.20.0 - limit to 10MB VLAN30 - 10.0.30.0 - limit to 3MB
They have a NETGEAR ProSafe VPN Firewall FVX538 on 192.168.1.1. They have 2 different wi-fi routers, one is static at 192.168.1.4, the other is not static.Someone donated a Linksys Wireless-B Broadband Router. They asked me to set that up. But i cannot get to the home page to change the IP address. 'multiple routers' it says to simply unplug one, so you can get to the config page at 192.168.1.1. I can not unplug the main router for the business, right? Do i need to change the IP of the Netgear temporarily? Will that bring down the network?
I need to NAT some subnets to one IP and other subnets to another IP. The range command want work because some of the subnets are out of order.For example subnets 192.168.1.0 - 192.168.7.0 and 192.168.25.0, 192.168.28.0 nat'd to 1.1.1.1. subnet 192.168.26.0-192.168.27.0 nat'd to 1.1.1.2
I've currently got my ASA (5505) serving a /28 public subnet. I've ran out of IPs, so my DC has issued me an additional /24 subnet that they have routed to my ASA. What needs to be done on my ASA so be able to use these new addresses? I've been trying to search and not been able to find a good answer (some say I shouldn't have to do anything, everything else references NATing, which I currently don't do and would rather not do).The servers I assign these to, I'd like them to have the public ip assigned directly to them.
I am setting up my home lab to practice and play around.I have VMWARE ESXi environment with two workstations as my servers.I would like to setup two domains with two domain controllers but i want each domain to have its own subnet.So this is my setup. I have Cable modem from cablevision , thay connects to my router which is Apple Airport which acts as the DHCP server. DNS server and default gateway. The network on the router is 10.0.1.xThen i have two switches . One is a 5 port unmanaged switch that connects to the three physical desktops .Then i have a Cisco small business switch SG200-08 that connects to my ESX servers and NAS. Now currently all is good and working but like i said all my machines physical or virtual get an IP that is 10.0.1.x and they get all this from the router. And i think i can setup two domains with two domain controllers without an issue and they will all get an IP address of 10.0.1.x. This is all good but i want to have one domain on one subnet and other on another so for example one domain will have 10.0.1.x and other 10.0.2.x. I am just not sure what i need to to get this setup like this. I know my SG200-08 supports vlans and i am pretty sure on the apple router you can only have one subnet i think. So can i do this with my current setup by setting up a DHCP server with two scopes ?
Here's what I want to do with my RV042: I have a bunch of devices, including a server, inside my network at 192.168.1.100
I've set up VPN using PPTP. It works, but if my clients have their own remote DHCP set up to 192.168.1.x, they can't get to the server. If their home DHCP is 10.x.x.x., everything works
I am considering changing my internal network to something obscure.
My server has two NICs. So I thought, I why not set one address up to 10.x.x.x But the two nets can't ping each other. I tried using "multiple subnet" on the RV042, setting up 10.1.1.1, but no luck.
I have a Windows 7 Pro Desktop with an on-board Ethernet and an Axis USB To Ethernet adapter. The on board Ethernet is configured as dhcp and obtain the address 10.162.146.123 with 255.255.255.0 subnet. The Axis USB to Ethernet adapter is static ip configuration with 10.38.25.37 and 255.0.0.0 as subnet. Under the adv settings I have also another ip 11.38.25.37 with 255.0.0.0 subnet. When the Axis is communicating 10.38.0.1 network I can not access the internet using the on board Ethernet 10.162.146.123. I have to disable either one of the cards to access one network at a time.
We have 4 RV 042 routers and cisco router at HQ, we have Site to Site VPN tunnels in between, All branch offices are connected to HQ via S2S VPN tunnels
now lets say i am branch 1, i can access 10.10.1.0/24 network but cant access 10.10.5.0/24 network, means i dont have branch to branch connection, it should be through HQ, means my RV042 at brnach should fwd all traffic to HQ for another branches also. Under VPN tunnel if i try to configure remote destination 10.10.0.0/21 its not allowing me it says network overlaping with local network, how i can sole it, I know how to do in cisco, we can permit those networks in access lists.
Is it possible to have multiple public IP addresses that are from different subnets going through one router? I have been told that this is not possible with most routers and that I would have to spend a lot of money on a router to be able to do it. I am still not totally clear on what defines a subnet even after reading up on them. What I am trying to achieve:
-My office has 10 computers.
-All would be connected to one router.
-My internet service provider has provided me with 10 public IP addresses, that are all very varied (which I asked for)
We have Point to point T1 environment where 3 additional WAN sites get internet access through our RV042. When we setup load balancing we have problems with https traffic, so we setup protocol binding for https and everything worked great from the local LAN. When trying to access https content from the remote LAN across the WAN the sites failed and I see no option to add additional subnets to the protocol binding. Is there a command line feature that supports adding additional subnets for protocol binding or is the local LAN the only option?
The ASA device is going to be the gateway for multiple distinct inside IP subnets. We can have have a unique outside IP address to correspond to each inside IP subnet if needed, but we need some means for a VPN client or a site-to-site VPN to have acess to a pre-definied IP subnet (i.e. if customer A establishes a VPN connection, they have connectivity to IP subnet X; customer B establishes a VPN connection, they have connectivity to IP subnet Y, etc.).Currently, the two inside IP subnets are 10.10.0.0/16 and 10.20.0.0/16. We will be adding more.The problem we are facing is that we cannot reach the VLAN 201 from the ASA we believe this is because. I have setup two addresses on port 0/1 Vlan1, 10.10.20.2 and 10.20.20.1 as an alias. How can we make traffic for the 10.10.0.0/16 subnet untagged and traffic for the 10.20.0.0/16 subnet tagged for VLAN 201.
I have setup 15 x RV180W's so far for a particular client.They have requested that we add a Corporate Wireless VLAN for their laptop users (not guests) and add a Special Use WiFi VLAN for a particular mobile platform that is being deployed (in this case we need 2 separate WiFi VLANs to ensure compliance).Also, none of the VLANs can talk to eachother and they have their own subnets.I have the Wireless and VLANs setup, no problem... but I am having an issue wiht the VPN settings.I have the wired network's subnet working fine. But I do not know how to add the subnets for both Wireless VLANs to the traffic selection.The IP schemes will not allow me to just select a large subnet... here are some examples:
x is the octet that defines the physical unit location (unit 1 = .23, unit 2 = .24, etc...) y is the octet the host.Since they are not in a contiguous block, I cannot just use a larger subnet mask.I can add multiple traffic selection rules to the ASA5515 at HQ, so that side of the tunnel is perfect... I just don't know how to add the three VLANs to the RV180. Is it as simple as using commas or semicolons?
I have a Cisco 2901 with the 4port gigabit ethernet switch module that I'm trying to get configured to have a seperate subnet for each port. So far I have it set up so each subnet is a vlan, then on each port I use the switchport access vlan command to tell it which subnet I want that port to be on. However, there is one port that I need to have 2 subnets on. The way I found to do that was to use switchport trunking on that port, but it doesn't seem to be working properly. how they would configure this? Right now I have vlan 101 as x.x.x.17/28 and vlan 103 as x.x.x.53/30. I think where I'm getting hung up is the proper association between the physical port and the vlan subnets.
We have a 6509 that was connected to 2 other locations(location A and B) and our local lan (location MAIN). We wanted to move the location A and B to a 3750 switch and only allow the traffic that needed to access our location MAIN to come through the firewall. The only problem I ran into is that before location A and B were on different interfaces so in the 6509 firewall the routes for traffic to our MAIN location was done by static routes.
because it has a static overlap, which makes sense to me, but my question is how do I configure the network to get this to work? Do I have to reconfigure my network and access-list? Do I need to add more ports between the 6509 and 3750? I'm not sure if this is the best way to do what we want. If something is not clear I'll try my best to explain the setup, but I just took over for our I.T. guy when he left.
I put 10.10.10.72 instead I should have put 10.94.10.72. the routed port is on a different subnet than the computer I'm trying to access.
We have RV 042 deployed for internet access/firewall purposes. Due to growing number for Wireless devices and also to separate WLAN traffic from wired devices, we have created a separate VLAN/IP Subnet for the wifi devices. We are having trouble accessing the internet from the WiFi VLAN/IP Subnet. Cisco 3750 is layer 2 and layer 3 device. We have VLAN 1 (10.10.10.0/255.255.255.0), all wired devices and RV 042 are part of VLAN 1. Connectivity to internet from VLAN 1 is good. VLAN 2 (192.168.1.0 / 255.255.255.0) was created for wifi devices, 3750 does the inter-vlan routing, I have enabled the multiple subnet feature on the RV 042 and added 192.168.1.2 / 24 to the subnet list, we still have issues accessing internet from vlan 2 devices.
As a workaround, I shutdown vlan 2 and added 192.168.1.0/24 as secondary address to the VLAN 1 interface on 3750 and i was able to access internet from 192.168.1.0/24 network with wifi devices also on vlan 1, we want wifi devices to be on separate vlan / ip subnet. Looking at the documentation for RV series routers, it talks about supporting multiple subnets access to internet by enabling multiple subnet feature but it doesn't seem to work.Are there restrictions on having multiple vlans?
3750 can not support multiple subnets in it's DHCP server pool config.
Is this an issue that can be fixed with a different iOS or is there a different Cisco switch that I can replace the 3750 with that will handle multiple subnets within an individual pool?
The thing is that I have private IP adresses on my LAN, and I have been issued a public IP network for my DMZ by my ISP.
Meaning I want to NAT my LAN but not my DMZ, but I can't seem to find a way in the 520 to do that. I can only find the oprion to turn off NAT all together.
I have an SA520 that is being used as a front end firewall. Behind it I have an IP PBX. The VOIP provides are registered and I can make outgoing calls. However It appears that the SA520 is either blocking or not routing the calls. I have opened the ports recommended by both the IP PBX and the VOIP provider. What do I need to do to make incoming calls through the SA520?
I have a pair of RV082 routers and I'd like to configure gateway to gateway VPN tunnel as described in a cookbook, "How to configure a VPN tunnel that routes all traffic to the Remote Gateway," (file name Small_business_router_tunnel_Branch_to_Main.doc). I followed this cookbook and found that my while the Main office has internet connectivity, the branch subnet doesn't have internet connectivity.
Routing does behave as advertised, where all traffic does go to the main office. However, the 192.168.1.0 subnet in the branch office does not get internet connectivity. I've read in other posts that the Main office router will only provide NAT for the local subnet, not the branch office subnet. Is there a way to configure the RV082 router to provide NAT for all subnets?
If not, which Cisco product will provide the VPN Tunnel connectivity as well as the NAT for all subnets? Can the RV082 be used as part of the final solution or are my RV082s a wasted expenditure?
Following is the configuration that I'd implemented, (real IP and IKE keys are bogus).
Gateway To Gateway Remote Main Office Add a New Tunnel Tunnel No. 1 2 Tunnel Name : n1-2122012_n2-1282012 n1-2122012_n2-1282012 Interface : WAN1 WAN1
i have a asa 5520 that is working with three zones DMZ, inside and outside.
my DMZ is for all my branches and it had a /24 subnet my inside had a /24 subnet and all was fine i could talk to branches and they could talk to me. i also had all the branchess accessing internet via the ASA which is at HO. i changed the subnets from /24 to /21 and broke everything
below is the configs for the asa ! interface GigabitEthernet0/0 nameif outside
Site A: ASA5520 VLAN data subnet 172.16.10.x/24 VLAN Voice subnet 10.0.0.x/24
Site B: ASA5505 Base license VLAN data subnet 192.168.10.x/24 VLAN Voice (restr) subnet 10.0.1.0/24
The callmanager is located on site A and needs to sent out DHCP-offers to site B through the VPN so the IP-phones can register to the callmanager. I got the VPN up and running for the data-subnet but i can't get traffic through the voice-subnet/VLAN.
Can the ASA's do the job or do I need to route traffic before the ASA's on both sides and sent it through the tunnel, configured both subnets as interesting traffic? Ofcourse the last situation I need to upgrade the license for the 5505 to gain more VLAN's.
I have two ASA 5510 in an active-standby cluster, not that I think that the fact that they are clustered will be of any importance here so feel free to think of it as a single 5510. The internet connection is delivered in a single RJ45 connection. To be able to use it with the cluster there is a simple unmanaged switch connected between the ISP and the ASA's. I have two subnets with public addresses, for simplicity lets call them 1.1.1.0/24 and 2.2.2.0/24. Default routers are 1.1.1.1 and 2.2.2.1 respectively.
Can I somehow use both these subnets in the ASA's? Im currently using the first subnet and use PAT to direct traffic to internal servers. But if I want to use adresses from the second subnet wont that mess up the routing, since there is no way I can specify the default router for the second subnet? I have as of yet not tried anything, Im just trying to plan ahead and I cant seem to wrap my head around how this could possibly be done.
Having trouble with a couple items. First of all, should I be able to ping the inside interface of the ASA from all internal subnets assuming all of these subnets/vlans are directly connected to the same L3 switch? I can ping the ASA inside interface from our L3 switch, but I cannot ping the inside interface from a host on a different internal subnet. I have setup static routing on the ASA [
route inside 10.10.96.0 255.255.248.0 10.30.1.1 1]and verified that I can ping the host [10.10.96.212] from the ASA inside interface [10.30.1.5]. The inside interface is on the 10.30.1.x/24 subnet. My host is on the 10.10.96.x/21 subnet. From the ASA I can ping 10.10.96.212, but I cannot ping 10.30.1.5 from 10.10.96.212. I can however ping 10.30.1.1 from 10.10.96.212.
This leads to my next issue, which is trying to setup the ASA to work concurrently with our current firewall. I'm doing this in order to transition to the ASA. I'd much prefer to cutover inbound NAT a little at a time vs. doing it all at once. Our current firewall is setup at 10.30.1.2 and this is the default route on our L3 switch (0.0.0.0 0.0.0.0 10.30.1.2). So my question is, if I setup an inbound NAT to one of our web servers on the 10.10.96.x subnet, will I be able to get it to route back to the ASA as opposed to ending up in asymmetric routing **** since the default route points back to our other firewall?
ASA 5585-x10, ver 9.1. I have about 10 public sub nets that will be used for NAT translation on the outside interface. These sub nets are different from the sub net the outside interface. Is there a way to advertise these routes using OSPF from the ASA?
I tried to redistribute a static route, but can't make the destination router an interface that is on the ASA. I don't own or control the upstream router.
I just got a Nook Color as a gift (nice huh?) I just bought my iPad2 in Jan. So now I've got Comcast cable with a Netgear N600 router and:
1 desktop Win XP sp3 plugged into router 1 desktop Win 7 usb wireless 1 HP laptop w/ Vista 2 Dell old laptops Win XP not used much Sony PS3 not on much iPad2 always on Nook Color AND a Roku always on
I think that's all. So I'm guessing all this will slow down my whole connection? My iPad is the fastest. My Nook is extremely slow. Maybe it's the B&N website? When I go to shop and even when I registered it, it says connection having trouble. I finally had to setup my account at BN with my desktop. The Nook wouldn't stay connected.
We are deploying two Cisco 5585 in transparent mode and multiple contexts. they are running Active-Active fail over.
There are a lot of V LANs need to be added in the contexts, we are trying to use least contexts to fulfill.
ASA supports 8 bridge groups for each contexts, and maximum 4 interfaces for each bridge group.
We have assigned four interfaces in different V LANs , set two of them as a pair with one IP sub net and the other two interfaces are in another IP sub net.
For example :
Bridge group 1:
inside1 and outside1 -------> 192.168.1.0/24 inside2 and outside2 -------> 192.168.2.0/24
However, we can only make one sub net(V LAN pairs ) work when the BVI is set to that IP sub net. If the BVI set to 192.168.1.0/24, the inside1 and outside1, the other pair not work. If the BVI set 192.168.2.0/24, then only inside2 and outside2 work.
Since the BVI can only be assigned to either of the sub net, Is it possible to make both vlan pairs work ? Or we only can have one sub net in one bridge group ?
