Hey guys, running out of time here... I think my last message didn't
make it to the list. Anyone see why my OPT1 (WIFI) interface is getting
traffic blocked at the firewall? (mostly return incoming traffic on high
ports, which means the standard client --> server/ server --> client on
web sites etc. is getting blocked.
What rule would tell the firewall to allow servers to send traffic back
to the client in this case, and why doesn't the LAN interface need it by
Thanks for taking the time to assist me with this small, probably pebkac
based error. Below is my config.xml. I have edited out any security risk
based fields, so as to make it "Google Friendly".
My overall goal is to have the WIFI interface be on a seperate subnet
with firewall rules blocking any interaction between it and the LAN
subnet, (along with some basic subnet masking to ensure a client doesn't
just try to change their IP address to the LAN subnet, 192.168.1.0.)
I basically copied the default LAN firewall rule to the WIFI rule list,
with the important areas (specifically where the interfaces are defined
in the rule) set to WIFI instead of LAN. I suspect the incoming rule
needed to allow webservers,etc. to communicate back to the WIFI
interface is missing. (usually on the return web port, some random high
end port number). If so, does the m0n0wall just assume that LAN needs
this rule, but doesn't list it in the config? If this is the case, could
you give me a reasonable rule to allow the return packet data to cross
the firewall to the WIFI interface?
Thank you again,

Sufficient detail to be able to tell you want the problem is. ;)
Easiest thing would be to post the entire interfaces and rules parts
of your config.xml. Or if you don't want them forever archived by
Google, you can email it to me offlist.
