I mounted a an IPSEC tunnel between a RUT950 and a Zyxel USG. The tunnel seems to work fine, but I think there is some kind of routing problem...
Zyxrl USG network: 192.168.3.0/24
The computer 192.168.3.121 must comunicate with the computer 192.168.5.10
Ping OK between computer 192.168.3.121 and RUT950 router 192.168.5.1 via the IPSEC tunnel
Ping OK between RUT950 router 192.168.5.1 and computer 192.168.3.121 via the IPSEC tunnel
Ping OK between Zyxrl USG router 192.168.3.1 and RUT950 router 192.168.5.1 via the IPSEC tunnel
Ping OK between RUT950 router 192.168.5.1 and Zyxrl USG router 192.168.3.1 via the IPSEC tunnel
Ping OK between router RUT950 192.168.5.1 and computer 192.168.5.10
But Ping does not work between computers 192.168.3.121 and 192.168.5.10
Using a Tracert we can see that from the computer 192.168.3.121 we get to the router RUT950 192.168.5.1
I think there is a return routing missing from 192.168.5.10 to the network 192.168.3.0/24 when using the IPSEC VPN on the RUT950...
Can anyone help me out with this? how can I fix it?
Hope you can help me,
