I need to connect to from my home office to work via a vpn. I have been given a xp laptop to perform that function. I tested it's settings at a friend's house and I could connect no troubles.
However back at home behind my linksys router (BEFSR11) it did not work.
I logged in as admin and there were no ports open under the advanced tab for the tunnelling to occur.
I opened 47, 50, 500, 1723 [Both - UPD & TCP] and pointed them at the IP address of the laptop from work. It still did not work.
I then did a port scan and found that only my ftp and http ports were open??
If you know of any doco/url for this sort of connection problem [installation of a vpn] I'd appreciate it.
