Dedicated DSL line for the Exchange Server
Hello.
Our entire company uses one DSL line. I would like to know how to setup our Exchange Server to use its own dedicated DSL line for sending and receiving e-mail (actually any Internet traffic). The rest of our computers and servers should continue to use our existing DSL line for Internet traffic.
Details:
+ Exchange Server 2003
+ 2 NICs
+ running Win2k3 server
+ NOT a DC
Thanks.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
If you have two DSL line, you have to routers, one for each line.
Outgoing mails:
The default gateway used by the clients or a web-proxy points to the first router
The default gateway of the exchange server points to the second router.
This configuration send all traffic (but not only mail) from the exchange to the second DSL line.
If you want to route only mails, but no other traffic from the exchange, you may have to use a dedicated mail relay server, which only handles mails with the default gateway set to the second router.
Incoming mails:
If you poll down mails from a provider, nothing else is to do as Exchange or the poll program will use the same gateway.
If you have external MX records, you will have to change them pointing to the new router. Dynamic IP addresses for incoming mails is not a problem, but more for outgoing mails, if not routed to a ISP.

Due to oversubscription of the ISP you may not see speed or reliabilty increases you anticipate.

I like your idea of plugging the dslmodem/router into our switch and giving it a local LAN address. I did an initial trial with one of the desktops and it seems to work. Since we have a static ip address, I just need to have our WebHost change the sub-domain pointer.
I'll keep you posted.

Most of the ISP's give u a dynamic IP Address and dont allow SMTP Trafic to prevent SPAM mails orginating from your connection.
