Hi :)
Allright, so, I've been trying to build a routing setup for some weeks now,
and after looking everywhere and asking for help, I still cannot find the
answer.
Here is what I want to do: source routing to 2 internet connections.
Basically, I want net1 to go on the Internet using gateway connection1 and
net2 to go on the internet using gateway connection2.
You have to know that both internet connections have dynamic IPs and I need
NAT on both.
So far, these are my not working config files (defaut gateway is
ip1/connection1).
em0 = inside interface
tun0 = pppoe DSL connection1 (default route)
tun1 = pppoe DSL connection2
--> /etc/ipfw.conf
#!/bin/sh
fwcmd="/sbin/ipfw -q"
ip1=`/sbin/ifconfig tun0 | /usr/bin/awk '/inet / { print $2 }'`
ip2=`/sbin/ifconfig tun1 | /usr/bin/awk '/inet / { print $2 }'`
lan1=192.168.0.0/24
lan2=192.168.1.0/24
${fwcmd} -f flush
${fwcmd} add 100 fwd $ip2 all from $lan2 to any out recv em0 xmit tun0
${fwcmd} add 200 divert 8669 all from $lan2 to any via tun1
${fwcmd} add 300 divert 8668 all from any to any via tun0
${fwcmd} add 400 allow all from any to any
--> /etc/natd_tun0.conf
interface tun0
port 8668
log_denied yes
log_facility security
use_sockets yes
same_ports yes
unregistered_only yes
punch_fw 10000:10000
dynamic yes
--> /etc/natd_tun1.conf
interface tun1
port 8669
log_denied yes
log_facility security
use_sockets yes
same_ports yes
unregistered_only yes
punch_fw 10000:10000
dynamic yes
I am really really looking for help here. If you know how to make such a setup
working, I would appreciate a hand.
Thanks in advance.
Regards,
Antoine
