ADSL Setup problem

[hplc.hplc]

Hi,

I've a customer environment with the following setup :

(Branch)Internal LAN->FW->ADSL Router->ISP->Internet->ISP->ADSL Router->FW->Internal LAN(HQ)

The branch need to setup a tunnel with the HQ with the help of the firewall (not a Cisco), then only traffic can go over to the HQ via the tunnel.

The tunnel can be setup successfully with the ADSL router in the picture, but traffic(the application -> Email, Printing) never goes thru (but icmp is alright, with a 30ms to the HQ). But when the ADSL router is taken out, everything goes smoothly.

I've nowhere to go.. There's only a access list on the router, that permits all the traffic.

Hope someone can help me with this.

P/S: Only the branch router is on our control.

Thanks in advance.

First you need to make sure that that traffic reaches ADSL router. Create two access links on ADSL router (I guess that is Cisco) and log all the traffic coming and leaving from Internal LAN.

What model is ADSL router ? Do you have IOS firewall on it ?

How come it works when you take ADSL router off, does Firewall have ADSL interface ?
