I set up a server about 7 days ago. VPN was working absolutely fine behind my linksys router. I could connect ,disconnect as many times as i desired. But from today I am unable to connect to my server via VPN i get the error 721 , i looked in the contribs and found that there is some bug. i have used the sme server iso 7.1 and since then not upgraded any modules from the net. the server worked fine for 7 days. pptp numbers of users set to 2. Please help how to resolve this issue.
