Trying to set up a VPN at our office. The connection is a verizon business
dsl with static ip. Server is Windows Server 2003. VPN is using L2TP/ipsec
with certificates. DSL modem is a Westell 327W configured in straight bridge
mode. Internet and LAN work great, the VPN can be access locally. Also if I
take a laptop and plug it in instead of the DSL modem and give it a static
ip in the correct subnet the VPN works (so filtering on the external
interface shouldn't be an issue). However if i try and access the VPN from
anywhere on the other side of the DSL I get error 678. Any ideas? Hoping
someone here might have heard of a similiar problem with these dsl routers.

Have you forwarded the port to inside computer?

When the DSL router is in bridge mode there are no options to do that. W2K3
has the 3 inbound and 3 outbound udp filters.
