Cisco RVS4000 port forwarding and VPN

Draiden85 · ‎06-15-2010

Hi everyone,

I have an issue to install a VPN for my company. Basically I need a VPN tunnel between two branches and the ability to remotly connect with laptops from outside. I think that 2 Cisco RVS4000 are the solution for now, but i can't make the VPN tunnel work. I tryed in local and they work quite well, but when i connect the routers to the Thomson gt585v7 for give them the internet connection, nothing seem work fine. Basically i got this device in front of the cisco gateway and i don't know what to forward to the cisco router to make the vpn work. I tryed to forward the port for https and the port 8080 and the http port 80. I can't access to the router remote setup anyway. I read that i can't have a NAT function before the cisco router to enable the VPN, but i don't think it's possible to pass a public IP directly to the WAN port of the cisco gateway.

To let you know better my configuration is LAN -> ciscoRVS4000 -> Thomson gt585v7 -> Internet <- Thomson gt585v7 <- ciscoRVS4000 <- LAN

And i wanted to know how many users can connect from outside ( and if is possible connect someone from outside )

thanks a lot for your help

I forgot to tell you that i manage to forward an apache server that is in the lan so basically the port forwarding for the two devices is working.

For The RVS4000, try the documentations here :

I tryed to follow that guides, but the problem is that i can't get the public IP, so i can't sele

ct the router from outside the lan. I tryed

to setup a gateway but i can't find it in the router configuration menu.

For adding informations the Thomson is a router itself, and so i'm stucked betweet the public ip and a natted one

Public IP -> internal ip -> cisco external assigned by thomson -> internal ip assigned by cisco

And on the other side is the same i can't turn off the thomson routing to use it as a normal modem.

From Data sheets of the RVS4000, it supports NAT-T.

Now all you need is for your Thomson device to be able to do something like what the PAT-router can do as illustrated here :

Good luck with it.
