The ipfw rules for the 'simple' case in rc.firewall were a starting point, but then I added a few additional rules from various spots on the net attempting to fix various problems. Any advice would be appreciated. I couldn't find exacly what the problem is. It looks oke for me. If you like to go on with this one you could try doing: 1. ipfw z 2. Try sending your mail 3. ipfw sh (and look where the packed gets blocked) 4. If you sloved the problem skip to the end 5. Add log to the rule and do 1-3. Then check /etc/security and look for the rigth packets and see what happens. What I like to do is offer you an alternative framework. I'll be in a better position to help you this way. For this first put these lines in your /etc/rc.conf. This will load the firewall rules from that file. firewall_enable=YES firewall_type=/etc/firewall.conf Then put these rules in your /etc/firewall.conf: # Select NIC (1 = internal 2 = external) add 00010 skipto 1 ip from any to any via rl0 add 00020 skipto 2 ip from any to any via vl0 add 00030 allow ip from any to any via lo0 add 0 deny ip from any to any A packet send from the XP box to the internet passes these rule twice because it goes through two NICs. # Internal NIC 19997 allow ip from 192.168.1.0/24 to any 19997 allow ip from any to 192.168.1.0/24 19998 reject log ip from any to any in 1 deny log ip from any to any out reject = deny + it tells the sender that no such service exist. That is smart for _you own_ computer. ## External NIC - Anti spoofing #add 20200 skipto 20300 ip from 192.168.1.0/24 to any in #add 20210 rejectip from any to 10.0.0.0/8 out #add 20220 rejectip from any to 172.0.0.0/12 out #add 20230 rejectip from any to 192.168.0.0/16 out #add 20240 deny ip from 10.0.0.0/8 to any in #add 20250 deny ip from 172.0.0.0/12 to any in #add 20260 deny ip from 192.168.0.0/16 to any in Afther everything works you can place your anti spoofing rules here and keep those packets from going into natd. Rules 200,240-260 can block you out and are optional. # External NIC - Natd 20520 skipto 20600 ip from me to any 20530 divert 8668 ip from any to any 20540 allow ip from me to any 20550 allow ip from any to 192.168.31.0/24 This acts like a stateful firewall (like below) for the lan. # External NIC - Stateful firewall 29800 allow tcp from me to any keep-state setup 29810 allow udp from me to any keep-state 29820 allow ip from me to any keep-state This allows packets out and responce back in. # External NIC - deny or reject everyting else 29998 deny log ip from any to any in 2 reject log ip from any to any out -- Alex Articles based on solutions that I use: http://www.kruijff.org/alex/index.php?dir=docs/FreeBSD/ ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Newbie:Home network mail forwarding
Hi,
I am new to unix but I have managed to setup a home network using
Free BSD. The
FreeBSD box is a gateway/firewall/router for my Windows XP box and a
wireless access
point. The XP box can access the web just great using the shared connection.
My problem is when email is used on the WindowsXP box , no messages can be
sent out. I can receive email from my ISP's pop-server just fine. I am
not sure if I need
to start some kind of mail daemon or what Is it my firewall
configuration
I have included some of my setup files, hopefully someone can tell me
what I am doing
wrong. Thanks in advance..

Thanks in advance.. I'm not a Unix developer, and *don't* play one on TV. I do run a firewall, though. My $0.02 : If you're using the default /etc/rc.firewall in simple configuration, you don't have a firewall rule to allow outbound connections to an SMTP server (Tcp port 25). Try issuing the following as the superuser on your FBSD box: $ipfw add 00023 allow tcp from me to any 25 setup and then see what happens from the Windows machine. Please note that 00023 is an arbitrary choice of rule numbers; you will want this rule fairly close to the top. You might do ipfw show and decide where the rule should fit before deciding what number to assign... ?
