Connecting to VPNs in JCC San Francisco

ok... working from a cafe today, the Jewish Community Center in San Francisco. And I ran into problems using my VPN connection. I connected to my IBM VPN but ran into all kinds of weird problems coming from a cache.opendns.com address telling me that it couldn't open webpages. Essentially, all internal addresses were not correctly resolved from that DNS or rather all DNS requests weren't routed to the DNS of the VPN. So I finally figured out how to connect to IBM's VPN. I just had to set the DNS of my wireless connection profile to IBMs DNS server 9.1.1.1 and all addresses got resolved correctly...
