Win2K NAT

By armand ·
We're running a Win2K Advanced Server for NAT. We've got 3 NIC's installed. 1 for our internal network and 2 Intel Adapters teamed for our public addresses. I've assigned 3 public IP's to the adapter team and assigned these to the NAT public interface pool.
Our application/exchange server is on a public network as such users have to go through the NAT box to download sofware or emails. This works fine for small apps but as soon as you start downloading big apps or email attachments it times out or gives a message stating that the network path is no longer available. Any ideas how to work around this as I don't have enough public IP's to give everyone and NAT looked like the ideal solution.
Thanks
Armand

Win2K NAT

It IMHO *still* looks like the ideal solution, once implemented right.
I guess it's a tuning problem with W2K doubling as a NAT server. First try to tune more, the support.microsof.com site no doubt gives some hints.
If that doesn't bring you far enough, consider a hardware router with NAT. Doesn't need to be very expensive (say $ 500 or so), and has 100% of its CPU time available for NATting as compared to Windows which can sometimes run into overload because of all the different server tasks.

Hope this helps,

If your Exchange server is on the public side, why don't you dual-hone it? if one of your NIC's goes to the public side, for laptops and employees in the field, and the other one is on the intranet, you have less of a chance of timeouts through the NAT, because you could tell everyone's outlook to go straight to the server on the intranet side...
OR... If you have a 802.1q capable NIC in the Exchange server, and a VLAN tagging capable switch, you could swing the IP's that way, but you're asking for the cheap way that way, and the port/NIC may get bogged down (depending on traffic)
Good Luck,
