routing problem

[Len Jacobs <ljacobs@mandala-designs.com>]

I had posted this query several weeks ago and am still struggling with 
this problem.

I have been running a 3.3 system with pf as a firewall and gateway for 
email and web servers with no problem. Yet, while trying to set up a 3.4 
system (generic kernel), with an xl and rl NIC, I am unable to get the 
local systems to get their packets sent out via the OpenBSD server.

In /etc/sysctl.conf, I do have the line:
"net.inet.ip.forwarding=1"

The server itself can reach internal and external IPs, the internal
hosts can ping the internal and external NICs of the OpenBSD server, but 
cannot reach the gateway IP address.

The (I think) relevant dmesg output re the NICs:
rl0 at pci1 dev 6 function 0 "Realtek 8139" rev 0x10: irq 11 address
00:30:1b:ae:a4:bf
rlphy0 at rl0 phy 0: RTL internal phy
"VIA VT6306 FireWire" rev 0x46 at pci1 dev 7 function 0 not
configured
xl0 at pci1 dev 8 function 0 "3Com 3c905C 100Base-TX" rev 0x78:
irq 10xl0: command never completed!
  address 00:04:75:8b:fd:14
exphy0 at xl0 phy 24: 3Com internal media interface

What am I missing or forgetting? It must be something obvious and yet is 
not apparent to me. Any suggestions will be welcome.

Thanks.
