Hi all, I'm trying to setup a gateway between an internal network using Vbox test machines of which one is a FreeBSD router/gateway. Being familiar with Cisco I know how easy this is to do but I think that I'm struggling a bit with the syntax. My setup is as so: Damn Small Linux (virtual machine) -> (em1) FreeBSD 8.2 (virtual gateway) (em0) -> internal network 10.100.100.2 10.100.100.1 172.16.7.136 172.16.0.0/20 My current configuration within the FreeBSD router looks like so: /etc/rc.conf: gateway_enable="YES" hostname="ROUTER.test.org" ifconfig_em0="inet 172.16.7.136 netmask 255.255.240.0" #em0_nat="NO" ifconfig_em1="inet 10.100.100.1 netmask 255.255.255.192" #em1_nat="YES" inetd_enable="YES" keymap="uk.iso" sshd_enable="YES" defaultrouter="172.16.0.1" ipnat_enable="YES" ipnat_rules="/etc/ipnat.rules" named_enable="YES" static_routes="net1" route_net1="-net 10.100.100.0/26 0.0.0.0/0" /etc/ipnat.rules: map tun0 10.100.100.0/26 -> 0/0 portmap tcp/udp 10000:65000 map tun0 10.100.100.0/26 -> 0/0 The router from DSL is set as 10.100.100.1 and it hits it without any problem... running a traceroute however gives this: ROUTER# ipnat -l List of active MAP/Redirect filters: map tun0 10.100.100.0/26 -> 0.0.0.0/0 portmap tcp/udp 10000:65000 map tun0 10.100.100.0/26 -> 0.0.0.0/0 List of active sessions: Something here isn't working and I'm not sure quite what it is :-( Can anyone help??? Thanks Kaya
