I have a vpn tunnel between two cisco routers sitting outside the firewall. They are using ipsec with a secret key. I have a different subnet at each end of the tunnel. Currently I can ping machines on the opposite end of the tunnel and I can do Remote control of workstations at the opposite end of the tunnel. However I can not "browse" the network, do DNS resolution, or access email. Any ideas? This is my first time working with a VPN. Thanks.
