When I successfully connect to a specific company's VPN, I cannot access any internal or external websites. A website request in Safari just hangs. All traffic is setup to go through the VPN and the IT person in charge says that everything should just work for me and he is at a loss as to what the problem might be.
- iMac running OS X (v10.5)
- Cisco AnyConnect VPN Client (v2.4)
- Verizon DSL (Westell VersaLink 327W, all traffic allowed, PPPoE)
- Connected wirelessly to DSL modem/router
- Ping www.google.com
- Traceroute www.google.com
- nslookup www.google.com
- SSH to internal server
- Ping internal URL
- telnet www.google.com 80
I've also tried Firefox and Chrome and experienced the same hanging. In fact, right before bed, instead of canceling the URL request in Safari, I let it sit all night out of curiosity and this morning it was still trying to contact the site.
I've tried using tcpdump to monitor the cscotun0 interface (added by the Cisco VPN client) but I'm not really sure what I'm looking for---I do see activity when requesting a URL in Safari.
How can I further troubleshoot this to determine the cause?
While connected to the VPN, I captured an HTTP request for www.google.com using Wireshark. Here is a link to a screenshot of the capture (sorry I cannot post images---not enough rep):
