2nd internet connection for steam DLC
Some background: I am part of a group that host a 150 ish player lan party. We have been using PFSense as a firewall for several events and it works well. I am trying to make it work better. At our last two events, we had two cable modems that were provided by a local cable provider. We were using the built in load balancing to split traffic up between the two connections. After digging though our traffic logs for the event and doing a lot of thinking, I would like to ditch the load balance and just put downloadable content for steam on one modem and let everything else use the second. What tends to happen is for the first 20 or so hours of the event, both cable modems are saturated with people downloading steam updates, games, and in game content that someone else in the room has so they can play together. The result is that both modems get saturated and things like web browsing and online games become difficult and hard to play. We have also noticed that some online forums and a few online games don't seem to do well with the load balancing. I am hoping that getting the load balancer out of there and getting crazy with nat rules will fix a few usability issues that we seem to have. Steam uses TCP ports 27014-27050 for downloads. How would I set this up?
WAN = Internet
OPT1 = TCP ports 27014-2750
Do I need to create a rule for each port or can I do a range? I am using 2.0rc1 and I don't see an option for a range. Am I missing something?
Further complicating things, the last two events, we had consecutive IP addresses, both with the same gateway. IE WAN is 192.168.1.10 with at gateway of 192.168.1.1 and OPT1 is 192.168.1.11 with a gateway of 192.168.1.1
LAN rule: outbound, TCP, if certain port numbers, use gateway 2 (associated with OPT1)
LAN rule: outbound, default, use gateway 1
The earlier rule takes precedence.
Thanks, I will give that a shot when I get home. Will I have a problem if both interfaces have the same default gateway? It would be great if I could set the default gateway to an IP address rather than an interface.
