Re: Interface state unknown using fw monitor Hi Stephan, one of my customers has a similar issue. he is using Nortel Contivity for specific users and this VPN tunnel passes through his Check Point Site to Site VPN (so VPN inside VPN). No VLAN define on the interfaces. This architecture was working with NG AI R55 and since the R62 migration, he has had this issue. In the fwmonitor, we can see unknown interface on the outgoing interface. We are still troubleshooting this issue without any clue. Maybe CP'TAC will find something. As a workaround we use a GRE tunnel to replace the Site to Site VPN. Has anybody encountered this issue also? Thx Tan |
