I recently moved my home firewall from an old B56 box (Gateway 400Mhz,

NIC, rge internal) also no changes to tcp settings.
To complicate matters, I was forced to upgrade an old Cayman 3220H
router to a Netopia 3346N. Once I switched to the Netopia, I noticed
while snooping the external interface, a few ICMP Destination
unreachable messages. I was able to ping and eventually connect to
the site that was showing unreachable. It wasn't noticeable to users
with the B56 firewall. but with B64 and B65,
tcp connections frequently stall, and it takes a few attempts with
firefox to establish the connection.
OpenSolaris.org is one of the sites that exhibits this behavior along
with msnbc.com.
I've set the MTU to 1462 on the external interface and disabled path
MTU discovery, with no success.
I'm stumped. What's changed between B56 and B64+ to cause this behavior?
This sounds like an intermittent routing problem. How are you
establishing your static routes?

Hi Bart!
The OpenSolaris router has one default route to the netopia in
/etc/defaultrouter.
My DSL connection provides 5 static addresses, the last one being the
address of the netopia. No NAT on the DSL, so it's the closest I can
come to a bridge with PPPoe.
Thanks for your help,
John
