We have 2 external ip numbers (one for the firewall/gateway, a.b.c.d , and one for our web/ftp server, e.f.g.h ) I am using a static mapping (e.f.g.h) for the webserver, and that works fine for traffic inwards. However when I use the webserver and go out to the internet, the world sees it as ip a.b.c.d, but I want them to see it as ip e.f.g.h. How do I do that? Here is part of my rc.conf : gateway_enable="YES" router_enable="YES" ifconfig_rl0="inet a.b.c.d netmask 255.255.255.248" ifconfig_rl0_alias0="inet e.f.g.h netmask 255.255.255.248" ifconfig_rl1="inet 192.168.1.1 netmask 255.255.255.0" firewall_enable="YES" firewall_type="simple" firewall_quiet="NO" natd_enable="YES" natd_interface="rl0" natd_flags="-u -m -dynamic -redirect_address 192.168.1.3 e.f.g.h" Thomas Hanson ------_=_NextPart_001_01C1D72D.9E447030 Content-Type: text/html Content-Transfer-Encoding: quoted-printable
