Hi, I have a lan to lan VPN between two vigor routers which works fine. I have added in a Zyxel USG 50 firewall and now can not access any shared data from one of the VPN sites. I can ping machines by name or ip address but not browse to any shares. I can however go out from behind the firewall to the other vpn site fine and browse the shared data there.

Site 1 Draytek 2820n - PPTP VPN to site 2 (Internal IP's: 98.0.0.0)

Site 2 Draytek 2600VG - PPTP VPN to site 1 (Internal IP's: 192.168.1.0, static route for 93.0.0.0 addresses to 192.168.1.0 (Tried it with and without this, but I know this works as the draytek is also a wifi access point and people connected to this can access the 93.0.0.0 network fine)), Zyxel USG 50 Firewall (Internal IP's: 93.0.0.0, WAN Configured on: 192.168.1.2 (Which is DMZ in the draytek)).

I am sure I am missing something like a firewall port to open but cant seem to find what? I have tried taking the static route out and also tried letting all traffic through the zyxel firewall neither made a difference.To clarify site 1 cannot access any shared data from site 2, site 2 can access shared data from site 1. Both sites can ping machines by name or ip address

Please help

Andy
