Establish Bi-directional Communication Between 2 Routers On 2 Subnets?

Sep 6, 2011

I have three routers and 2 ISPs but I'd like to focus for now on a configuration with only one ISP provider. Here is my environment:

Netgear Cable (CBVG834G) wireless routerON the cable router are connected multimedia type equipments (TV/ IP set top box/ IP amp ) located on the family room DHCP ON (because I can't get internet connectivity when I assigned Fix IP address I come to that later) IP Adress:192.168.1.2 DHCP range:192.168.1.10/ 19 Reserved IP : 1292.168.1.10 for the Dlink 4 DEV a connected D-LINK ( DIR-855) wireless router.mainly PCs, NAS (x2) located on the first floor. DHCP ON Lan IP Adress: 192.168.0.1 DHCP range:

192.168.0.100 / 120 WAN Ip address : 192.168.1.10 6 PCs are connected

Everything works fine from an internet connectivity standpoint:

DEVx can connect to internet fine
PCx can connect to internet
PCx can access DEVx

Now the issue DEVx can't access resources from PCx!

Cisco :: Communication Between Subnets On 5510

Sep 13, 2011

I am working on a Cisco 5510 with multiple interfaces and requirements. I have experience with Cisco IOS, but not too much with the ASAs. I seem to be getting a bit confused on the NATing and ACLs on a firewall that was started by another employee, who is no longer here. With my current config I can get the firewall in place (we are currently using an older PIX) and most basic functions work except for two key things: 1) communication from the finance interface to the inside interface. The finance subnet has some restrictions that you will see in the ACL- we are trying to limit connections to the those systems, but they need to be able access an e-mail server on the inside. 2) communication from the DMZ interface to the inside interface. Maybe related to the first problem?

Cisco Routers :: RV220W - Communication With KIES Application

Apr 26, 2012

I recently bought this router for its great throughput and V LAN capabilities. It replaced a standard Linksys DIR-655.But now I am having trouble connecting my Samsung Galaxy2 (Android 4.0.3) telephone to my computer. Telephone is connected to WI-fi and computer is connected to wired  LAN. When starting Kies on my telephone (this is a web server app) it tells me to connect to http://192.168.1.202:8080/  on my computer. This is the correct IP address for the telephone (I have reserved it on the router)  and firewall is OFF in windows 7.  But there is no response with Firefox or IE8.   I have not changed anything on either the computer or the telephone since I replaced the router, so the problem must somehow be linked to the router.
 
Both telephone and computer are connected to the internet OK.  I can even remote control the computer from the telephone using the VNC app on the telephone!So the network IS working. The problem is only related to the communication with the Kies app.

Cisco Routers :: RV042 Cannot Establish PPPoE But PC Can

Jun 17, 2012

I have a RV042 and want to establish one WAN connection via PPPoE. I enter Username and Password, Keep Alive, MTU=Auto. The router does not get an IP address (0.0.0.0) and the log says: "[pppoe] sending PADI", "last message repeated 5 times". What is confusing me is that a PC connected to the RV042 (and a DSL-Router operating in Modem-Mode "PPPoE Pass-Through") can establish a PPPoE connection with the same Username and Password. Why can the PC connect via PPPoE, but the RV042 can not?

Cisco Routers :: RV220W Cannot Establish PTPP VPN Connection Over WAN

Sep 22, 2011

I am not able to establish a PTPP connection with my iPhone over WAN. When I am in my local Wireless LAN it works nice using the external FQDN of the RV220W. But when I test the VPN access over 3G (meaning I am coming in over the WAN port) I get and error message that the connection to the PPP server could not be established.
 
Some more Info

- Running latest firmware
- Port 1723 is open to the Internet
- ISP doesn't filter anything
- No Firewall settings blocking anything at the moment
- Nothing in the logs indicating what the problem is
 
So what needs to be done here to get it running over the WAN port and not only over the LAN ports?

Establish A Simple LDP Targeted Session Between 2 Indirectly Connected Routers?

Nov 19, 2012

I'm practicing MPLS and wanna establish a simple LDP targeted session between 2 indirectly connected routers. when establishing this session with loopback IP address of routers, the session is established, but when I tested this session with another router's fast0/0 that is MPLS enabled, the session did not established. I wonder, if a targeted LDP session, needs to be established between 2 IPs that are selected as LDP IDs of respective routers. I made routers to use their fast0/0 IP addresses as LDP ID and the session was established.

Cisco Routers :: Unable To Establish VPN Between RV180W And IPad Via PPTP

I have tried to make a VPN connection between RV180W and iPad with PPTP. I have enabled the server, set the address range, added and user and enabled it.
 
I entered the same information into iPad but when I try to start the VPN, iPad just tried to make connection and finally fails with an error stating that PPP server cannot be reached.
 
I think the devices are able to make some kind of connection as if I change the gateway IP address incorrect, I get a different kind of error message. I also tried to reboot the router...

Routers / Switches :: Separate Subnets Not Working As Described

Jun 25, 2011

I'm trying to set up 2 separate networks in my home, both of which have access to the internet through a single ISP.I have set up my networks using 2 routers as described in the "Version 2" scenario found here: url...The problem is, a computer connected to the LAN side of Router 2 is able to ping and map shared folders on computers connected to the LAN side of Router 1. According to the writeup (last paragraph), this should not be the case.I have been over the setup multiple times to ensure it is per the writeup but each time, I am able to ping and map.Is there some additional router/computer settings that I may be missing?FWIW, here's my take on what is happening (with the ping): When a computer on the LAN side of Router 2 (submet 192.168.1.x) does a ping to a computer on the LAN side of Router 1 (subnet 192.168.0.x), Router 2 sends the request to its Default Gateway (since it's a different subnet).Router 1 however, recognizes this as its LAN side subnet and forwards the request to that computer. The ping response is then routed back from Router 1 to Router 2.

Cisco Routers :: Can RVS4000 Be Used To Bridge Subnets

Dec 10, 2012

At the small church I attend, and where I'm the IT guy, we have an RVS4000 router which has worked well for us including the VPN capability. Our internet connection is through AT&T (not my choice) and last week we had to switch from DSL to U-Verse because AT&T is doing away with the former.

Unfortunately as part of this switch, the old modem was discarded and an NVG510 installed. The NVG510 is a combo modem/router. But since it doesn't have VPN capability and is not as good a router all around as the RVS4000 (even though the 4000 is an aging device), I am trying to run both.
 
I finally figured out how to set up IP Passthrough on the NVG510 so now VPN is again working to the RVS4000 so that's not an issue. We do have a couple of PCs that are in a room where no wired connections are possible so they are using wireless. But they are not very close to the wireless antennas so they don't have the greatest throughput. The NVG510 does have wireless capability and is physically located to where it would provide a much better signal. However, the NVG510 will only use a 192.168.x.x subnet and our LAN is setup for 10.x.x.x. I'm not about to change the LAN as it runs a Windows domain with enough equipment that I don't want the exercise of changing subnets.Can the RVS4000 be setup so that it will route domain traffic between the 2 subnets? As it is now, connecting a PC to the 192.168.x.x subnet on the NVG510 allows it to have internet access but it can't access domain resources on the 10.x.x subnet. I don't understand networking well enough to know why this won't work. I know it can because when I worked for a large corporation, they had different subnets that were routed so that PCs on one subnet could be on the same Windows domain as PCs on another subnet and all access resources on both subnets.
 
The RVS4000 may be capable of doing this but my limited knowledge of networking (I know servers, not switches, etc) means I'm not sure of what I see on the router to know if it can do it or not.I'd be appreciative to know first off if the RVS4000 can do it, and secondly if it can, then how to set it up. I've worked with the RVS4000 since we got it 3+ years ago so I'm fairly familiar with it, I just don't know the rest.

Cisco Routers :: RV042 Multiple Subnets

Jan 22, 2013

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.

Cisco Routers :: RV180 NAT Five Static IPs To 5 VLAN Subnets

Feb 14, 2013

I have five static IPs that I would like to fully utilize, by NAT'ing them to internal VLAN subnets.I read that the RV180 can do this, but I am having difficulty in finding a working recipe.I have assigned xxx.xxx.xxx.2 to the RV180 WAN interface.
 
I have created four additional VLANs 2-5 and assigned to ports 1-4 with subnet interfaces 192.168.2.254, 192.168.3.254, 192.168.4.254. and 192.168.5.254,I have set the default VLAN to untagged on all ports. VLANs 2-5 are set to tagged for their respective port (1-4) and exclude for other ports.I have set DHCP relays to 192.168.1.202 which is my DHCP, DNS, AD services.
 
I read some months ago that when the first static IP address is assigned to the WAN port, that the VLAN ports will accept tagged packets on their ports and NAT them to the respective successive static IP (sounds a bit like magic to me). Regardless, I read that the RV180 can provide VLAN subnet NAT to up to 5 static IP address. I am not looking for 1 to 1 NAT, not the same.  I want to perform NAT on the four additional VLANs in the similar manner that VLAN 1 (default DMZ) IPs are NAT'd to the static WAN address. As in everything outbound on 192.168.1.0 is NAT'd to xxx.xxx.xxx.2
 
Additionally I would like all DHCP assigned by my DHCP server which I believe is accomplished with the DHCP relay setting on all five VLAN subnets, which point to the DHCP server 192.168.1.202
 
Lastly, I am trying to configure VPN connectivity into my DMZ network. I have configured a few accounts, enabled for PPTP. I have configured PPTP and am issuing 192.168.1.70-80. The VPN connection seems to work great without the use of Cisco quick VPN. I can see the remote picking up the 192.168.1.71 IP address as the VPN connection is made. From the remote I can ping IP addresses on the DMZ subnet 192.168.1.X   How can I configurer the Cisco RV180 PPTP server to provide the DMZ DNS ipaddresses? These addresses need to be 192.168.1.201 and 192.168.1.202
  
I feel I am almost there, in working out the VLAN subnet to Static NAT. I suspect it will be some routing configurations. The ISP business gateway on the WAN side that I point my router to which is owned by Verizon, is xxx.xxx.xxx.1 I have a /29 making IPs xxx.xxx.xxx.2-6  available to me.

Cisco Routers :: RV042 VPN Tunnel For Multiple Subnets?

Aug 5, 2011

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.

Is there a command line feature that supports adding additional subnets for protocol binding or is the local LAN the only option?

Cisco Routers :: RV180W VPN Configuration / How To Choose Multiple Subnets

Jan 4, 2013

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:
 
Wired VLAN: 10.10.x.y
Corporate WiFi VLAN: 10.15.x.y
Special WiFi VLAN: 10.18.x.y
 
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?

Cisco Routers :: RV110W Unable To Access Other Subnets When Using PPTP VPN

Jan 1, 2013

I've encountered a problem when using PPTP VPN to access my network. I can connect in and able to ping the hosts connected to the RV110W. [code] On the local network, I am able to ping the hosts in 192.168.250.x from 192.168.251.x and vice versa.Static routes are configured to ensure that all networks are reachable.The problem comes when I tried to VPN (PPTP) in from a remote location using the Windows XP's built in default VPN dialer.When connected, I can ping all the hosts on 192.168.254.xxx segments, but when I tried to ping the hosts in 192.168.250.xxx and 192.168.251.xxx segments, I get a request timeout.
 
The routing table on the RV110W shows the gateway for 192.168.254.240 (the VPN IP address) as 0.0.0.0 and interface is WAN.What am I missing and how should I configure the RV110W so that I can access the other subnets through VPN?

Cisco Routers :: 3750 / RV042 And Multiple LAN Subnets Access To Internet

Nov 27, 2011

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?
