D-Link DI-804 and Linksys BEFSR41 NAT problem

I have a Linksys BEFSR41 as my firewall/router. Everything works fine
and I got great performance compared to my old D-Link DI-804.
The D-Link DI-804 did not work if my Linux box has over 128MB memory
which is a very wired problem and took me two years to finally figure it
out.
The new D-Link BIOS fix the problem, but the performance is terrible.
I got average 900ms latency for pinging www.yahoo.com, compared to
150ms-300ms with Linksys BEFSR41 (V3).
My problem is, the Linksys do too much NAT for me. It translate my
local connection (say from a windows box on 192.168.1.4) to 192.168.1.1,
which is the Linksys itself. The problem is, it does not always do that.
Here is my pop3 log:

Aug 30 12:02:53 w3 ipop3d[23523]: Login user=brian host=home2000.eatools.com
[192.168.1.4] nmsgs=0/0
Aug 30 12:02:54 w3 ipop3d[23527]: Login user=marry host=linksys.eatools.com
[192.168.1.1] nmsgs=0/0
Aug 30 12:02:54 w3 ipop3d[23527]: Logout user=sales host=linksys.eatools.com
[192.168.1.1] nmsgs=0 ndele=0

All 3 accounts are from the same windows box, but have 2 different IP
addresses on my
Linux.
Any help will really appreciated.

Thanks

Eric

Why do you have 2 IP addresses on your Linux box? That may have been
causing your latency problems with the Dlink. You need to do special
routing per Adv-Routing HOWTO if a box has more than 1 nic or alias on the
same network. Otherwise you would arbitrarily get 1 IP or the other,
depending upon which is quicker to respond to the arp request. Doesn't
that sound very much like your problem?

Sorry that I didn't make myself clear. The IPs are from my the other
machines, a windows box.
The Linux box has only 1 ip and 1 nic (192.168.1.2) The log file is from my
linux
box.
The windows box has ip address 192.168.1.4
Linksys box: 192.168.1.1
Why I get both 192.168.1.1 and 192.168.1.4 on my pop3 log from Linux Box ?
