(ASCEND) Pipe75 and Ethernet data filters.
I've been unable to get data filters working for Ethernet. If I
set any non-empty filter in Ethernet/Mod Config/Ether options, I
find that I can't make any connections at all from the ethernet.
If I set a filter who's input and output filters are all Valid=No,
then it works fine. If I set a filter with a single in and a single
out filter like:
Valid=Yes
Type=IP
Ip...Forward=Yes
Ip...Src Mask=0.0.0.0
Ip...Src Adrs=0.0.0.0
Ip...Dst Mask=0.0.0.0
Ip...Dst Adrs=0.0.0.0
Ip...Protocol=0
it doesn't work (I cannot access the router from the ethernet).
My goal, here, is to setup a filter which explicitely denies certain
packets, allows certain others, and denies all that are not handled
by a specific rule. For instance, deny all ethernet-out packets
with src on the LAN, and all ethernet-in packets with dst on the
LAN, while allowing ethernet-in with src on the LAN and ethernet-out
with dst on the LAN. Relatively simple stuff, but if I can't even
say "allow everything to pass" successfully...
Thanks,
