I have a Windows 2000 SBS running Exchange 2000 for internal and external
mail. IAS server is also installed using an old Netgear router/gateway to
do the PPPOE. Clients are using Outlook 2002 on Win98 and WinXP Pro
workstations. Recently external emails stop sending and receiving but
internal emails all seem to work. I was not the one that installed server so
I'm not 100% sure how everything is configured so I thought maybe I could
get some troubleshooting advice. I checked services and logs all seem to be
functioning ok. It looks like this server is getting messages from another
server using etrn/turn through pop.business.earthlink.net. I believe it
was configured this way since earthlink does not offer static IP's. It
looks like exchange grabs mail from the above server and deliveries to users
on LAN. Does anyone have any suggestions on why external emails might not
be working.??

Also I'm toying with idea of removing the IAS server and just use a linksys
router to make things easier. Would removing IAS server have any impact on
exchange i should be aware of ??? (of course port forwarding but other than
that).

thanks in advance
rob
