I have a weird forwarding problem. It _seems_ that IP forwarding between
ethernet and tokenring isn't working.
Is anyone running a Linux 2.0.36 (or 37pre) with both ethernet card and
tokenring and doing forwarding with it?
The network is like this:
192.168.100.0 ----- 192.168.100.252 (eth0) Ethernet
| (containing 192.168.100.253)
Linux (which is an OfficeConnect)
|
192.168.123.0 ----- 192.168.123.252 (tr0) Tokenring
Modules load okay. (3c509 and ibmtr)
ifconfig shows correct info.
route -n shows correct info.
using: ipfwadm -F -p accept ; ipfwadm -I -p accept ; ipfwadm -O -p accept
using: ipfwadm -F -f ; ipfwadm -I -f ; ipfwadm -O -f
using: ipfwadm -F -i accept -S0.0.0.0/0 -D0.0.0.0/0 -v -o to log all packets
Pinging from any ethernet or tokenring connected PC to the router works fine.
(on the interface within that network only)
Pinging through the router does not work. syslog shows the packet arriving
in the logfile. syslog does NOT show packet leaving.
It receives packets from both networks. It can be reached by both networks,
but it doesn't forward.
I've included my .config just in case. On a virgin 2.0.36 with two patches
from www.linuxrouter.org being:
ftp://ftp.xtdnet.nl/pub/linux/linux-router/linuxrc-always_2-2.0-diff
ftp://ftp.xtdnet.nl/pub/linux/linux-router/initrd-archive_2.1_2.0.35.diff
I'd really like to hear from someone who has a similar setup working.
