2 Wan Connections to 1 XG

TommyGunnah

 Hey everyone,

 

First time posting on here and im wondering if there is a way to setup load balancing amongst two carriers?

 

Current setup we have 1 200mb line through Carrier #1 and with Carrier #2 we also have a 200mb line

 

With Carrier 1 we were given a  static range of 192.168.1.0 /28

Nothing with second carrier as this was just installed.

 

I'm not sure how should I go about setting this up or if this is even possible.

 

Thanks for your input!

    Hi  

    Welcome to the Community!

    Yes, you can absolutely load balance between 2 WAN links.

    Simply, add both Gateways to your firewall. By default, they are added as Active Gateways that Load Balance by default.

    For detailed instructions, please read our KB Article: Sophos Firewall: How to configure gateway load balancing and failover

    Karlos,

     

    Thank you for your prompt answer..

     

    What about if we have NAT statements that are going through our 192.168.1.0 /28 network? Since the static range was assigned by Carrier #1 how would the load balancing happen if I add another wan connection from Carrier#2 which has no static assigned and just a random public address to it.

    Hi Tommy, 

    It'd be best to point your DNAT rules towards the statically assigned WAN. 

    Then you can create an additional firewall rule above your default rule that specifies your internal servers that these NAT statements point to as the source. For Primary Gateway, select the statically assigned WAN. This will ensure that all traffic to and from these internal servers will always use the same WAN while the rest of your traffic is load balanced b/w the 2 WANs.

    Thanks,
