Route Multiple Subnets

[Mattz]

Hi All,

I have used PFsense for a long time and need to convert a Debian router to Pfsense with Failover.

The config that I have now is routing a multiple subnet that I need to setup in Pfsense, the question is what the best way is.

My config is as follow where the virtual interfaces are routed over eth0 using IPv6:

auto eth0
iface eth0 inet static
        address 62.xxx.xxx.xxx
        netmask 255.255.255.128
        network 62.xxx.xxx.x
        broadcast 62.xxx.xxx.xxx
        post-up /sbin/iptables-restore < /etc/iptables
        post-up ip -6 addr add 2001:7b8:3eb::1/64 dev eth0
        post-up sleep 40 && /etc/init.d/aiccu start
        post-up sleep 120 && ip -6 route add 2001:7b8:3eb:1::/64 via 2001:7b8:3eb::2
        post-up sleep 120 && ip -6 route add 2001:7b8:3eb:2::/64 via 2001:7b8:3eb::5
        post-up sleep 125 && echo "1"> /proc/sys/net/ipv6/conf/all/forwarding

auto eth0:198
iface eth0:198 inet static
       address 62.xxx.xxx.xxx
       netmask 255.255.255.128
       network 62.xxx.xxx.x
       broadcast 62.xxx.xxx.xxx

auto eth0:32
iface eth0:32 inet static
       address 62.xxx.xxx.xxx
       netmask 255.255.255.224
       network 62.xxx.xxx.xxx
       broadcast 62.xxx.xxx.xxx

auto eth1
iface eth1 inet static
        address 87.xxx.xxx.xx1
        netmask 255.255.255.252
        gateway 87.xxx.xxx.10
        post-up /usr/sbin/ethtool -s eth1 speed 100 autoneg off duplex full
        post-up ip6tables-restore < /etc/ip6tables

Is there a special way to do best or just add the subnets and make the routes ?

I just setup the IPs and create the routes. I am not as familiar with IP6 routing as I should be, but I would imagine it works similarly. The eth0:XXX is an IP Alias in pfsense 2.0 and higher. You just have to translate a bit from Linux to BSD style of rules.
