HI
I have setup a L2L VPN between Cisco 857 (ADSL modem/router) in a branch and the Nokia IP130 Firewall at the main office. I am having the follwowing issues and I will appreciate your input
1) I would like the machines inside the remote office (LAN2) to connect to the main office (LAN1) for AD, but to use its own ISP gateway for Internet access.
At the moment, it seems like all traffic has been redirected through the VPN. ie - a PC in LAN 2 with DNS server pointing to reach ISP's, can't reach the Internet. Using a packet analyser, i can see that DNS requests are sent, but replies are not coming back. I figure that they might be stopped in the Nokia Firewall Gateway in the other end, to which i have limited access to check the logs.
I have also debugged ip packets at the router, and see no activity of any ACL stopping the reply packets.
The interesting parts of the Cisco configuration are as follwos:
--- NAT setup
ip nat inside source route-map NONAT interface Dialer1 overload
--- Route-map (I have read mixed posts saying that sometimes this approach does not work)
route-map NONAT permit 10
match ip address 101
----
access-list 101 remark NONAT access rule excludes IPSEC connections from NAT
access-list 101 deny ip 192.168.2.0 0.0.0.255 192.168.1.0 0.0.0.255
access-list 101 permit ip 192.168.2.0 0.0.0.255 any
I will appreciate some help with troubleshooting this issue. I can post the rest of teh config if necesary.
Many thanks !
