Zone-based firewall problem !

rvr_76bg — Mon, 11 Mar 2019 14:14:25 GMT

Hello,

I have problem with zone-based firewall on Cisco 2821 Router. This pretty new feature doesn't work for me. On the router I have one internal gigabit0/1 Interface which is in zone â€œINâ€ (in private network), gigabit0/0 Interface in zone â€œOUTâ€ (in Internet) and one VTI in zone â€œINâ€ (to be able to communicate with g0/1 without any problem, it carries OSPF over VPN). I have the following zone-pairs created:

zone-pair security sdm-zp-self-out source self destination out-zone

zone-pair security sdm-zp-out-self source out-zone destination self

zone-pair security sdm-zp-in-out source in-zone destination out-zone

The VPN is passing traffic, because the routing table is updated and I see all routes coming from the other site of the VPN. The problem is that I cannot pass IP/TCP/UDP traffic beyond the routers (in the private networks) on both sides. May be I missed a zone-pair? Please help. The problem is a bit urgent for me and any help will be highly appreciated.

Regards,

rvr

Please provide the configuration of the router.

Also, if you could post the output of the IP INSPECT LOG DROP-PKT.

Thx

Well, just as additional information, I had the same problem once where the VPN tunnel is established but I am unable to pass traffic between the Local LAN and the remote LAN.

In order to make it work, I did an access-list from the LOCAL LAN to the remote one and I put it on the zone-pair that is from the out-zone to the self zone.

I hope it helps.
