Have you tried shutting down iptables while connected through the VPN and see if DNA queries work? -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Gavin McDonald Sent: Thursday, June 08, 2006 3:18 PM To: 'General Red Hat Linux discussion list' Subject: Cisco VPN problem with DNS Hi list, I have a client with a RHEL ES 3 server, 64-bit on Pentium D-930. We have tried Cisco VPN Client v4.7 and v4.8. The problem is as such: The cisco VPN client connects successfully, and IP connectivity is established. the RHEL client can connect to all remote servers by IP. However, DNS is non-functional. some digging shows that /etc/resolv.conf is not updated correctly by the VPN client. Where this really gets strange though, is that even after correcting resolv.conf to point to the DNS server, (Which he can ping and even `tracepath <DNS_IP>/53`,) DNS lookups still fail. he's been using /etc/hosts to define remote hosts, and name lookups for servers defined as such work fine. I've checked his iptables, and unless I'm mistaken, the first rule should exlude that as the culprit: > Chain RH-Firewall-1-INPUT (2 references) > target prot opt source destination > ACCEPT all -- anywhere anywhere this rule should catch and allow ALL traffic, right? So at this point I'm stymied. I have now tasked our cisco rep with verifying the VPN server-side setup, but it appears that even if the VPN were to hand the DNS address correctly, DNS would still fail for a reason that eludes me. (as manual edits to resolv.conf fail to work.) I hope you guys can see something I missed, Regards, Gavin McDonald ======================== EVI Logistic Enterprises email: me@xxxxxxxxxxxx phone: (604) 313-3845 -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
