Re: FreeBSD routing between 2 interfaces
You forgot natd. Am guessing your DSL or cable modem is doing NAT and assigning an address to your FreeBSD system. No the modem assigns IP to the 192.168.0.1 router, which in turn acts as gateway for the rest of the network. I only have 1 real IP address. It seems I have NAT already on the 192.168.0.1 and will now have to put another NAT scheme into 192.168.0.3 machine? Perhaps, I should just create static routes using the route command in freebsd?

Re: FreeBSD routing between 2 interfaces
Yes I realize about the 10.0... and 192.168 not being routed matter. Previosly I always setup the network but never run out of IP address in the same range(192.168.0.*). It happened this time. Therefore I created the 192.168.1.* network but now it wont route. I can use NAT for that purpose but that would defeat communication between the 192.168.1.* and 192.168.0.* networks(there are a bunch of ftp and samba file/print servers in the 1.* network). I mean if I use nat: 192.168.0.* Connect 192.168.1.* = No success 192.168.0.* Connect 192.168.1.* = Success On Tuesday, 30 September 2003 at 21:33:43 -0400, [EMAIL PROTECTED] wrote: Dear FreeBSD users, I urgenly need to connect 192.168.1.* network to the internet. What am I doing wrong? You're assuming it's possible. It's not. Addresses in the range 192.168.x.x are explicitly not routed. See RFC 1918 (http://www.cis.ohio-state.edu/cgi-bin/rfc/rfc1918.html) for further details. You're not very clear about your router, but I assume it does NAT for you: to connect an RFC 1918 network to the Internet, you need to use some form of Network Address Translation (NAT). Theoretically, you'd need to do the same at the junction between the 192.168.0.x and 192.168.1.x networks, though you might be able to fake things by choosing 23 bit net masks.
