Multiple routing tables by LAN address solution?



  • I've been using Linux VMs for a routing via VPN solution with multiple routing tables by source address.  I would like to consolidate to a single pfsense instance with OpenVPN…

    Before I spend a lot of time learning and trying in pfSense, can (and how) pfSense do this Linux equivalent?

    [user@host ~]# ip rule list
    0:      from all lookup 255
    32765:  from 192.168.0.176/29 lookup 10
    32766:  from all lookup main
    32767:  from all lookup default

    [user@host ~]# ip route list
    10.21.1.4 dev tun2  proto kernel  scope link  src 10.21.1.3
    192.168.0.0/24 dev eth0  proto kernel  scope link  src 192.168.0.2
    169.254.0.0/16 dev eth0  scope link
    default via 192.168.0.1 dev eth0

    [user@host ~]# ip route list table 10
    98.138.252.38 via 192.168.0.1 dev eth0
    192.168.0.0/24 dev eth0  scope link
    default via 10.21.1.4 dev tun2

    Explanation:  This is routing config above on my VPN gateway (192.168.0.2).  The default gateway and Internet router is 192.168.0.1 with a WAN interface.  10.21.1.4 is the remote VPN tunnel endpoint and default for table 10.  Table 10 applies to only traffic going to and from hosts 192.168.0.176/29 on the LAN.  All traffic to and from other hosts on LAN route through default 192.168.0.1.  98.138.252.38 is a public address and host on the Internet as an exception to table 10 rules.
