i have a openBSD 3.3 as a transparent firewall and it was just working fine,
today i setup IPs on its interfaces and made it a gateway as well with NAT
functionality . what i see now is a very large delay time on the inetrnal
interface of this machine ( 2000-5000ms!!!)

the hardware is a pentium celeron 500 with 196MB ram
with two 10/100 network cards

is this due to my hw performance or sth else is wrong?

Try changing ethernet media from (most likely) 'autoselect' to something
like '100baseTX mediaopt full-duplex'. Use ifconfig -m <interface> to
see what the driver supports.

Partly incompatible link pulse (NLP, FLP) implementations are actually
quite common, and typically results in performance degradation. I'm not
sure why such a problem would surface only when the interface has an IP
address, but I guess it could possibly be caused by a driver issue..
