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
