Two ISPs one Server

uws4ks — Wed, 17 Jul 2024 11:58:33 GMT

I have recently added a second ISP to my office and it works great on failover.

But now I have a Server on the first ISP and in case of failover, I need the traffic to go through the second ISP.

Could any of you show me the configuration process to achieve this? How can resolve this ?

Thankyou in advance.

You have to create multiple NAT rules.
This is covered in the product documentation: https://sc1.checkpoint.com/documents/R81.20/WebAdminGuides/EN/CP_R81.20_SecurityGateway_Guide/Content/Topics-FWG/ISP-Redundancy-Configuration.htm?Highlight=isp%20redundancy

I assume its active/backup scenario? If so, link Phoneboy provided would help. Well, even if its load sharing, its covered there. Maybe if you can send basic diagram, we can confirm the steps.

In case of a failover , second ISP takes over and it works good except now NAT rules need to be made for the second ISP so the VPN server will be connected to it.

Who assigns your public IP?
If it's the ISP, then you need a public IP from each and a NAT rule for each one.
If you have provider-independent IP space (rare these days), then this may not be necessary.
