Title: Different Outbound IPs on multiple IPs in main uplink Post by: sseitz on Sunday 07 June 2009, 04:27:33 am Hi,
i've recently introduced a new server in ORANGE which is also reachable via RED (main uplink) by using a ALL:ALL Portforwarding Rule. RED holds 6 IP's via "main uplink". I configured one IP as usual and five "additional". All of these IP's are in the same subnet. If I connect via RED to this new server in ORANGE, everythink works as expected. If the server starts an outbound connection by itself, it's always routed via the first IP of the "main uplink". I'ld like to ask if it's possible to have this machine routed via on of the additional IP's? I did some tweaking on console with eth3:1 eth3:2 and static routes which seemed to work, but I'ld like to configure it persistent (and always visible) via the web configurator. I've also tried to add an additional uplink to the same interface, but it looks like every uplink wants its own interface ...

Adding a SNAT Rule solved this issue. Title: Re: Different Outbound IPs on multiple IPs in main uplink Post by: itguy12 on Friday 21 August 2009, 11:54:57 pm Can you be more specific? I have the same issue (multiple IPs on RED, all traffic is going out the primary). How did you setup your SNAT rules?

add RED[your_Special_RED_IP]:ALL -> Your_local_Server:ALL 2. Firewall -> Portforwarding/NAT -> [Source NAT] add : Source [Net/IP] -> You_local_Server Target [Zone/VPN/Uplink] -> Uplink main [ RED ] Service/Port left as it is. NAT [NAT] to Sourceaddress [Uplink main - IP: your_Special_RED_IP Position: As First Rule add: Source [Net/IP] -> Network/IP Field left blank Target [Zone/VPN/Uplink] -> Uplink main [ RED ] Service/Port left as it is. NAT [NAT] to Sourceaddress [Uplink main - IP: your_DEFAULT_RED_IP Position: As LAST Rule Apply Rules ;) |
