Hi,
Im hoping some one can help me out here or give me some guidance??
This is what i have...
Cisco 2600 router x.x.x.193 ---- eth0 Bridge eth1 ------ Hub ---- x.x.x.195
The bridge has 2 broadcom gigabit nics that i can talk to other nic with
with a normal nic setup and connect out to the net over the cisco router.
I have 2.4.18-24 and have not patched it at all, this came straight from
redhat only.
I set up the bridge, with no stp and br0 having no ip, eth0 & 1 also have no
ip set.
I can now ping from x.x.x.195 to .193 and out over the net but when i do
anything else except for ping/arp I only see traffic passing into the bridge
and never returning to it.
if i change the bridge for a bit of wire, between the router and the hub it
all works?
Now for the real info >
