I use advanced outbound NAT (to access my dsl modem). I'm not sure what you
mean regarding a similar inbound NAT setup, but I think the answer is no. I
ruled this out though, as mentioned in my original mailing, as I disabled
all that and used a stock configuration of m0n0 1.22, with those options
being disabled by default.
I should mention too, I'm not after a solution per se, just like to know the
reason, if it is indeed because of m0n0wall's SPI is doing its job, and the
software is really at fault (if anyone has a home-grade router with NAT,
UPnP, SPI, I'd love to hear from you!)
