join:2005-09-17 | Port forwarding with two routers... I have an internet DSL router with DHCP enabled for LAN connections. I have a LAN connection going from that router into the WAN port of a Cisco RVS4000 router. The Cisco router is the primary router for our network and handles DHCP. Two questions...
1. How do I do port forwarding to the Cisco router when it has to go through the DSL router first?
2. How do I make the VPN function work on the Cisco when it has to go through the DSL router first?

| business or residential?
is the dsl router also your modem/gateway? if so:
1. put that in bridge mode and let the cisco do pppoe, dhcp, vpn, port forwarding, etc...
if it isnt the modem/gateway, take it out of the picture and use the cisco.
you will have issues with double NAT, dual dhcp, and dual port forwarding with two routers. no need for two. |

join:2005-09-17 | Sorry, I should have painted a more full picture after reading your response..... Yes the DSL is the modem/gateway. The problem is there is another entities router, marked "Hall", that is working off of this same modem. So there are two separate private LANs working off of the single DSL modem so I can not just bridge it over and use only the Cisco....
Here is a picture that sort of represents the setup..... The "work" router is the Cisco of ours.

Stone Mountain, GA | You would need to forward the ports in the main router to the WAN IP of the RVS4000. Then in that router forward to the local IP. |

Hmm unless it has some sort of passthrough capability for VPN tunnels I would guess SOL. but I know poop. My advice is to
a. get your own internet connection
b. buy a set of IPs from the provider and separate the two offices that way. |

Do you have another, stand-alone modem? If so you might try using the cisco device to face your ISP so your VPN tunnels could be reachable to the outside world. Then you'd have to enable the other router for work to allow VPN pass-through. Also - are those the actual networks you are using internally? 192.168.0.0, 192.10.10.0 and 10.227.0.0 ? |

You may want to see if you can set the Cisco as a DMZ in the edge router (internet router), and then if the other office needs port forwards, simply forward the ports they need over to them instead of you. Port forwarding and VPNs is a trick i've never been able to easily pull off myself. |
