Remote VPN on Cisco RVS4000 router

Hey, All

Need help here for the wierd issue.

I configured a RVS4000 router to work a VPN terminator for remote users, like traveling or work from home staff. The Cisco quickVPN utility works as it shows VPN connection is successfully connected. However I can not ping any IP  address in my office network.

The laptop is windows 7 64bit. The office network subnet is 192.168.1.x/24. Home network subnet is 172.24.105.x/24.

I also did "route print" after quickvpn showed me successful but I do not see anyroute about 192.168.1.x.

Any suggestion where to check?

BTW, I openned QuickVPN as administrator and disabled windows firewall while using QuickVPN.

Remote VPN on Cisco RVS4000 router

Hi Shuai, the likely problem is, the devices you're trying to access have a firewall or domain blocking access. When you have a VPN connection, a domain controller see the VPN as a public connection. Additionally, things such as Windows firewalls do not accept inbound connections from different subnets. Lastly, UNIX boxes, would require the ip routing exceptions in the firewalls.

While, To my knowledge, once Remote VPN connection is done, there should be some device assigning new IP to work for VPN tunnel OR some new route for VPN tunnel on my laptop. But I do not see those after I connect with the QuickVPN.

Shuai, the router does not assign an IP for any vpn connection for this model. It is why your local LAN IP must be a different subnet when connecting to the router.

Ok, my home subnet is 172.24.105.x/24 and office subnet is 192.168.1.x/24. I can not ping or rdp to any host on 192.168.1.x once VPN is connected.

As stated originally, it is likely because of a firewall or domain issue (if you have a domain controller). Disable the Window firewall on the computer you're trying to access, then you should be able to ping at the minimum.

That is probably not the case.

The firewall is turned off on server/domain already. Between 2 servers inside office network, ping is fine.

Should there be any route for the VPN once it is connected? Otherwise how does computer know where to send traffic to in order to reach office network?
