Hi! I tried to make port forwarding to server in internal network, and nat for users in same network. Just port forwarding is working fine, but if I enable masquarad for internal network, I'm losing connection to redirected servers. What is wrong in my script? Thank you. out=192.168.2.1 ext_i=ep0 int_serv_1=192.168.1.1 port_1=80 int_serv_2=192.168.1.2 port_2=25 ########################## forwarding ############################### ipfw add 1000 divert 8888 tcp from any to $out $port_1 via $ext_i ipfw add 1100 divert 8888 ip from $int_serv_1 to any via $ext_i natd -p 8888 -n $ext_i -redirect_port tcp $int_serv_1:$port_1 $port_1 #-------------------------------------------------------------------- ipfw add 1500 divert 8889 tcp from any to $out $port_2 via $ext_i ipfw add 1600 divert 8889 ip from $int_serv_2 to any via $ext_i natd -p 8889 -n $ext_i -redirect_port tcp $int_serv_2:$port_2 $port_2 ############################ NAT #################################### ipfw add 0900 divert 8887 ip from any to any via $ext_i natd -p 8887 -n $ext_i ipfw add 65000 allow ip from any to any To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
