After connecting to VPN: can ping, can't browse
Hello. Once I connect to a VPN, I am able to ping machines by domain names, but I am unable to simply browse the internet.
Error:
HTTP/1.1 504 Fiddler - Receive Failure
Content-Type: text/html
Connection: close
Timestamp: 18:39:00.500
ReadResponse() failed: The server did not return a response for this request.
This stopped working sometime in the last 3 months, but I blamed it on my ISP. However, I am now away from home, and able to use the VPN from a different machine, but not from mine.
I tried disabling my Kaspersky Internet Security 2010, but this didn't help. I've had this anti-virus software for a year now, and it was working before.
The biggest clue is in my router's log (read from the bottom up) (this gets added to the log once I connect to a VPN)

Which got me to check my ipconfig.

Could you tell me what all these tunnel adapters are?
Then, I checked my port forwarding table on the router, and I saw some (probably UPnP) entries. My machine is 192.168.1.4

Hi
Thanks for the reply. I cannot control what happens on the server, but I imagine everything works on that side, as I can connect to the VPN from other machines. I've done steps 2 & 3, and for step 4:
If I wanted all traffic to go through the vpn, would I have to 'route add 0.0.0.0 mask 0.0.0.0 <MY GATEWAY>', 'route add 0.0.0.0 mask 0.0.0.0 <VPN SERVER>', or something else?
Thank you,

I mean what you suggested is step 2 or 3. I've done that, but now I'm not sure how to add routes so that all traffic goes through the vpn
