I've recently set up a lan to lan vpn with a remote office with only four users. Using the vpn server facility of two Vigor 2600 ADSL routers everything seemed to go fine, it's only after a couple of days that we've noticed that if one user is using outlook to collect his/hers email that no-one else has any access to the exchange server at the same time. It's as if outlook has hogged all the available bandwidth on the one machine. Has anyone else come across this and did you find a solution?
