On our work network we have a number of public IP's. I have placed a Linksys BEFSX41 at one of the public addresses and the other one at home behind another linksys firewall.
I can sucessfully make the vpn tunnel and everything is working fine from the home side of the network. I have a voip phone that connects perfectly to the ipbx at work, can remote desktop etc perfectly. here is the problem... once the vpn tunnel is established on the work side of the network local devices can no longer resolve (some) websites. i can get to google.com etc but not other sites. https sites seem to work. what is strange is that it doesn't appear to be a dns issue because even if i go to the ip addresses of the websites they do not appear, can't ping, tracert etc. I have tried the mtu settings to no avail. if i disconnect the vpn then the problem dissapears.
i am really confused now.
any help greatly appreciated.
