Using wildcarded hostnames in routing.



  • I plan to set up a DUAL WAN router using this software with the goal of improving latencies of gaming servers between 2 ISPs.  I am exploring my options

    Is it possible to specify in a wildcard hostname in the destination field as an outbound data rule.
    e.g.

    Source - 192.168.3.1
    Port - *
    Destination - *.xyzisp.com
    Gateway - 192.168.1.254

    Source - 192.168.3.1
    Port - *
    Destination - *.abcisp.com
    Gateway - 192.168.2.254

    If not are the IP blocks for an ISP publicly available?

    Furthermore in the process of port forwarding, can I fwd the same port on both external interfaces (WAN1, WAN2) to the same machine.

    e.g.

    WAN1:27015
    WAN2:27015
    Both fwd information to PC1:27015

    Finally, I plan to slap in 3 NICs into the machine and a normal wireless NIC to make this work like a normal router.

    WAN1 = 1NIC
    WAN2= 1NIC
    Outgoing to switch = 1NIC
    Interface for wireless devices to connect = 1 Wireless NIC

    Do I have the necessary NICs or does wireless require something special.

    no you cant do this. you can only have an IP address or subnet  in the destination. 
    if you ping abc.xyzisp.com you will see the ip address of the host. you can use this to policy route your traffic.
    if its a friend that you are playing with then ask them to lookup their ip address (http://whatismyip.com) and route the whole /24

    yes that is fine.

    I doubt that this is possible.
    They would have to route through your system which ISPs don't do.

    You don't have the capacity on your internet link(s) to provide such a service if you're asking this. No pun intended, only trying to judge from observation.



  • I am sorry if I misrepresented the matter, I don't intend to become a route for the general public.  Anyone using the game servers on my network will be the persons affected by the routing.

    I think i'll use sai's suggestion and route based on the entire /24 of a specific IP.  It would have been nice to go to some registrar and ask them for all the possible IPs that my ISP can use.



  • Actually you can! Learn about the AS assigned to your ISP.



  • Excuse me, the AS?





  • I believe I got it!
    Thanks for the great advice.
