Cisco Routers :: RV042 Firewall Multiple External IP Addresses
Oct 6, 2011
if possible with the RV042.Primary External IP address uses port forwards for some ports, all okay.I would like to have other external ip addresses assigned to machines on my lan.Basic host multiple web servers, on different IP addresses, using port 80. [code]
From what i am reading, it looks like the RV042 can do this, but I am not real clear what my rules should look like.
I would think my high priority rule for each external IP address would be to deny all traffic first for each machine on the lan.Then create one entry with source 202.x.x.2 port 80 -> 192.168.168.2 ?
How should I set my rules to do this, and what settings should I have on the Nic of the second machine?

Trying to get a service setup with a third party to access our system (ERP web service to access our ERP data, making data available to customers and vendors via internet). They require that I setup four external IP addresses to have access through the firewall. I haven't figured out how to do this. I'm using a Linksys WRV200 router.

In setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.

On the System Summary screen in the Port Statistics table when you click on one of the Connected links the pop open window does not show the IP address of the connected device when using IPv4. Where can I find this?
If the devices are using static IP addresses and not getting them from the DHCP server they do not show in the Client Table under DHCP Status.
If they are know MAC addreses because they have been assigned to static IPs on the DHCP setup screen they will not show up in the Uknown MAC Addresses pop up window.

I recently cut over from a WRT54G to a RV120W. I am having an issue where I type [URL] (for a server running on my network) in my web browser while on the internal network and it always comes back with the router login page. Basically it is supposed to go out of the router and then come back in on the public IP address and hit that server. There was a function on the WRT54G called "Filter Internet NAT redirection" which when turned off would allow this to happen. I am not seeing a feature like this on the RV120W

I've installed RV042 for a client of mine. For next two months everything worked without any problems. The issue I've been experiencing lately is when I assign a static IP address to the PC it won't have internet access. Once I allow it to have a dynamically assigned IP then it works fine. The IP I assign isn't part of the DHCP range.

How do i tell my firewall to start listen also on another outside ipadress assigned by my ISP? I have it used on other firewall right now. So my steps would be shutting down ip address assignment off old firewall interface. Assign that ip address to ASA5510 outside interface and configure NAT.

I have an unusual deployment scenario which may require the use of a SRP-521W, the scenario is as follows:Temporary Setup:Cisco 857 As the ADSL router until Ethernet Hand-off is installedMultiple IP addresses delivered on the ADSL WAN serviceCisco 857 put into Bridge Mode and connected to SRP-521W WAN portCisco 521W handles the Authentication and RoutingCheck Point Firewall System connected to SRP-521W LAN-1Check Point Firewall has WAN IP 203.XXX.XXX.XXXCisco UC-540W Connected to SRP-521W LAN-2Cisco UC-540W has WAN IP 203.XX.XX.XX If you understand the above scenario, I am curious if this can be done and if so how? I need to keep the networks totaly separate and the only thing they would have in common is the Cisco SRP-521W.It should also be noted that the SRP-521W Is being used because the ADSL service is only temporary whilst the Fibre Build is completed and the carrier provides an Ethernet Hand-Off, then the Internet service will change to this type of presentation and the ADSL router will be relegated to the dark world of loneliness.I have gone through the router and have been playing around with the settings, the issue Is I have nothing in the LAB work up that can allow me to replicate this environment and test it before deployment... So, how to reduce the amount of trail and error I have to encounter to get it to work.

I am a total Cisco novice who has just had a ASA5505 installed to replace a linux freeware firewall (smoothwall).I'm told that the 5505 can't port forward traffic (e.g. ssh) from two external IP addresses to two internal destination machines via the same port # (22 in this example).

If there are any small business routers that offer one-to-one NAT? I have several public IP addresses assigned to me by CenturyLink. I have two servers that provide email and web hosting for two different domains. I want to put the client machines on one VLAN (VLAN Z) and assign it a public IP address (to keep server traffic separate). I want to put each server on its own VLAN (VLANs X & Y) and assign each server its own public IP address. I need the router to be able to provide a firewall and port forwarding for each VLAN. I also need to be able to route traffic between VLANs so the clients on VLAN Z can access their email and the websites on VLANs X and Y. I also need to be able to route DNS traffic between VLANs so each server can provide name resolution for their respective domains.
So, is this possible with a small business router or do I need to look at something different? I'm fairly certain this configuration is not possible with my current Cisco RVS4000. What it boils down to is I need a router that is capable of having multiple public IP addresses on the same interface and to forward those public addresses to private VLAN subnets. This would be one-to-one NAT if I understand it correctly..

We have just setup a new RV042G firewall. The customer has multiple public IP addresses and we need to allow RDP access for at least 2 of the Public IP addresses. I only see a way to open ports for the one IP assisgned to the WAN. I temporarily did a one to one NAT for the second public IP to NAT to the private IP but that pretty much opens everything which is not ideal from a security standpoint. How can we setup multiple IP addresses on this firewall?

The client has a Cisco RVS4000. There are 3 Internet devices need to be accessed from the outside and will use one public IP for one device. I don't see any options to setup on Cisco RVS4000 to do 3 NATs. If Cisco RVS4000 doesn't work in this situation, which router will do?

I have purchased a subnet of 8 private IP addresses from my ISP. 109.x.x.128/29.The ISP has placed a juniper router within our data centre which is routing purely from 109.x.x.206/30 to 109.x.x.128/29 with the ip of fa0/1 set to .129.
I have linked a cisco 5505 to fa0/1 of the juniper from fa0/0 and configured its IP to .130. I have configured NAT to translate our client pool 192.168.16.x /24 address' to the internet.
Is it possible for the 5505 to route / map my remaing private IP addresses through its external port? I have tried creating a seperate VLAN for a DMZ for our servers to sit within but am returned with a subnetting error as VLAN for my external port is all ready configured within the same subnet.

I have a customer that has an RSV4000 Router. The customer has also purchased a block of 5 usable public IP addresses. I need to be able to assign these public IP addresses to printers either by configuring a static IP on each printer directly or thru IP mapping or some other method. Does the RSV4000 support using multiple public IP addresses and if so what configuration is needed in the router for the printers to be seen by the outside world.

I have an ADSL connection and have configured the PPPoE subinterface on WAN1 (ADSL) this connection has a static IP, and I know that the ISP gives that to me through DHCP however I have 4 or 5 additional IP addresses also provided to me on that same link, and they are not given to me via DHCP.
How do I configure this router to have multiple fixed IP addresses on a PPPoE interface?
I also need to port forward some ports for each of the IP's but I assume this will be easy after i have the IP addresses setup.

I am trying to configure a BT Business ADSL Router (BT2700HGV) to work in bridge mode in front of a Cisco RV120W router and cannot get this to work.I have followed numerous posts I have come across in configuring the BT router for bridged mode and this has been configured as follows:
ATM Encapsulation - Bridge LLC
DSL and ATM - VPI=0, VCI=38 (also tried VCI=35)
ATM PVC Search - Disabled
Connection Type - Direct IP (DHCP or Static)
Disable Routing - Yes
There are also some other options on the same configuration page for 'Broadband IP Network' (which I have left on DHCP) and also a 'Public IP' which has been left blank. After setting the above options this removes the LAN DHCP configuration, the PPPoA logon details and sets the internal IP address of the BT router to 192.168.1.254.
My understanding of 'Bridge' mode is that this router will now act simply as a modem and configuration details such as logon details and WAN IP address information are configured using the Cisco RV120W router?The configuration of the Cisco router is as follows:
Internet Connection Type - PPPoE
Username and Password set
Authentication Type - Auto-Negotiate (options here are PAP, CHAP, MS-CHAP and MS-CHAPv2)
Routing Mode - Router (Other option is 'Gateway (NAT))' - I have tried both options
The WAN interface on the Cisco router is connected to one of the LAN ports on the BT router. The 'Broadband' light is on the BT router but the 'Internet' light isn't. The WAN status on the Cisco router is 'Connecting'. I am sure I am missing something simple.We have been assigned a range of static IP addresses from BT so am trying to get these working too (x.x.x.24/29 - 5 usable statics), another option available (other than PPPoE) for configuring the WAN interface on the Cisco router is a 'Static IP', not sure if this is the correct option but have tried messing with it, I have tried assigning a static IP from the range given to us (.30 - the router address specified by BT) along with the subnet mask, however don't know what to put as the default gateway, would this be the peer address (but assume that would change anyway), in any case, using the 'Static IP' option does not give an option to supply the BT logon details which I assume is required?
In bridged mode, what is the peer address assigned to, the BT router or the Cisco router?Does the BT router need to be configured with a public IP address?

I am trying to get two external addresses to PAT to different ports on the same address in the dmz.
Object NAT is configured as follows:
object network Obj-192.168.1.20-1
nat (dmz,outside) static Obj-External-1 service tcp https https
object network Onj-192.168.1.20-2
nat (dmz,outside) static Obj-External-2 service tcp 2000 https
Obj-192.168.1.20-1 and Obj-192.168.1.20-2 contain the same host address.
The idea being that traffic destined for Obj-External-1 on port 443 will be forwarded to Obj-192.168.1.20-1 on port 443. Traffic for Obj-External-2 on port 443 will be forwarded to Obj-192.168.20-2 on port 2000.
Traffic for the first object, Obj-192.168.1.20-1, works but traffic for the second does not.

I'm currently replacing my ASA 5505 with a 5510. I have a range of public IP addresses, one has been assigned to the outside interface by the setup wizard (e.g. 123.123.123.124 ) and another I would like to NAT to an internal server (e.g 192.168.0.3 > 123.123.123.125). On my asa 5505 this seemed fairly straigh forward, i.e. create an incoming access rule that allowed SMTP to 123.123.123.125 and then create a static nat to translate 192.168.0.3 to 123.123.123.125. Since I've tried to do the same on the 5510 traffic is not passing through so I'm assuming that the use of additional public IP addresses is not handled in the same way as the 5505? I also see that by default on the 5505, 2 VLANs are created, one for the inside and one for the outside, where as this is not the case on the 5510. Is the problem that VLANs or sub-interfaces need to be created first? I'm doing the config via ASDM.
Everything else seems to OK i.e. access to ASDM via 123.123.123.124, outbound PAT and the site-to-site VPN.

I have a RV042 with multiple subnet, 192.168.10.0 and 192.168.9.0. 192.168.10.0 is assigned to the LAN, 192.168.9.0 is created under multiple subnet. Both subnet can access Internet by accessing IP address, but 192.168.9.0 cannot access Internet by using host name. It looks like DNS is not working for the 9.0 network.

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.

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
10.10.1.0/ 24 HQ
10.10.2.0/24 Branch 1
10.10.3.0/24 Branch 2
10.10.4.0/24 Branch 3
10.10.5.0/24 Branch 4
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.

We have setup a new internal web server so now we have two internal web server and both or hosting sites on port 80. Currently we have port 80 forwarding to one of the web servers and users are able to hit it from the outside.
Is there any way to configure the RV042 to route web traffic to the correct web server by using the site name or dns? If a user puts in the address{URL}, be routed to one web server but if they put in {URL}, be routed to our second web server. I've checked with our vendors and the both web servers applications need to run on port 80. If we have forwarding setup on the RV042 to forward port 80 to web1 then users can't access web2 from the outside?

I'd like to set each individual LAN port with different address i.e. LAN 1 192.168.1.1 and LAN 2 10.1.1.1 instead of using the multiple subnet feature and having all ports replying for the addresses created.

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.

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?

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?

I am working on replacing our Checkpoint Firewalls with ASA's, and am running into the following NAT problem. On some of our Checkpoints, there are external NAT's that are mapped to multiple internal hosts based on ports.Is there any way to translate that to the ASA? I'm not sure the ASA will let you have multiple internal hosts mapped to one external IP using static NATs. The main issue, is these are alarm panels that receive data from external hosts (the traffic is initiated externally on the Internet) so I can't use dynamic PAT with this.

I have a 1760-v router set up at my home lab and I am unable to access IP addresses outside my local network. I have my Cisco router's fast Ethernet port connected to a small net gear router which then connects to my cable modem. The Cisco router is able to ping local address fine, but when I try to ping an outside address or domain name it times out. However, when I am at the CLI and type something like Ping { URL}, it resolves Google's IP address but it will not ping it. I have IP DEFAULT-GATEWAY and IP NAME-SERVER both pointing to my net gear router and pointing to my ISP's DNS server.

I recently bought my daughter a refurshed dell 17" laptop which has Windows 8 home edition on it. She also has another smaller laptop with windows 7 on it, an X-box-360 and a PS3 all connected to this RV042 Business router.
I do not have access to the firmware version of the RV042. I believe it was updated in 2011 or early 2012.
We found out that with the RV042 firewall set to ON, she is UNABLE to hit her college website with the new win 8 computer
She CAN go to the college web site with the smaller win 7 computer when the firewall is off or on.
The win 8 computer will allow google searches, but when you click on any of the links, it will not load.With the win 8 computer, facebook will not load, MSN and Hotmail will not load.
Disable firewall, and most (if not all) items that did not work, magically DO work when the RV042 firewall is disabled for the win 8 laptop.
Having issues with with win 8 home edition and the RV042 firewall enabled? Is there a "simple" cure for this, other than slicking the laptop and putting win 7 on it?
