Re: creepy iptables problem.. please help

>> iptables -A FORWARD -s 192.168.199.253  -j ACCEPT << doesnt work

Don't you need a -p tcp between the FORWARD and the -d / -s?  For other
iptables commands anyway it insists to have the protocol named before it
can interpret the addresses you are giving.

Also you mentioned earlier 192.168.199.254/24, AIUI that is evil, you
must actually use 192.168.199.0/254 to give that properly in CIDR.  Of
course maybe you just typed it in the email and it is fine if used in CIDR.
