Afternoon, im having a weird issue that ive not seen before and wondered it anyone had some ideas.

All sites have draytek 2820 Routers

Site A - Spain

Site B - UK
Site C - my house :) 2 miles away from site b

so until last night, the vpn was working as normal.

This morning, the vpn tunnel dropped. i checked all setting on both sites, nothing has been changed.

Site A router wont dial B just blanc refuses.

Tried L2TP (what it normally uses) and PPTP, neither work

Ipsec creates a tunnel but wont flow traffic nothing on tx or rx logs ....

So i tested site A - C .... Works fine (A always dials out into B)
then tested C - B using the same settings for both tests. Works fine....

so both routers are functioning perfectly ... so why dont they want to talk :|

Site A is on Globatel site B is on Nildram

Im so confused as to why they work by proxy but dont wanna by themselves :s

Weirder still the individual pc's at site A will dial up via L2TP into the site B router no problems.

What on earth is going on HELPPSSSS PLIXXXXX
