Is it possbible to bind one SRCDS on the both WAN interfaces? I've two ISP and wanna to bind my public on both WAN IP adresses.. SRCDS over nat, physically servers' IP it's a local address. I use dst-nat for the adress translation from wan to lan and lan to wan. Connection established, ports opened on both WAN interfaces(via routing) but srcds can't reserve both wan addresses..

Connection to Steam servers successful. Public IP is WAN2

or

Connection to Steam servers successful. Public IP is WAN1

But never I can't see it on both interfaces. crap :\

Sure it works, but you need to forward cs:go ports from IP2 to IP1

Example of script:

#!/bin/bash
LANG=C; LC_ALL=C; export LANG LC_ALL
clear

You need to replace IP2 and IP1 with your ip's

[ZASTRELIS]

I understood. But one problem, I use a mikrotik :\ Topology of this looks like: "WAN1" -> connection marked as "WAN1_conn", then route marked as "to_WAN1" of connection is "WAN1_conn" then routed table switch flow to the static route "WAN1" where to_WAN1 looks xD I don't understand nothing! But two days in ROS and it works fine. And this two days and at end of them where I can understood that problem. This problem not in IPS balancing or NAt or something else, the problem it's a SRCDS and I know how fix it, but can't do that on mikrotik ROS ((((((((

No, SRCDS doesn't have support for either multiple bind addresses nor multiple public addresses.

it's I already understood

[xkonsole]

You actually don't even need a srcds on the other host. Just a set of dst-nat/netmap actions.

[ZASTRELIS]

1ISP netmap, 2ISP with dst-nat or using manual redirection from 2ISP to ROS gateaway then from gw-ROS to local servers' addrr
