SMB1530 - Second ISP has no internet under Load Balance option

bcmario — Mon, 09 Oct 2023 14:08:52 GMT

I have two servers which are directly connected to the LAN interface of the firewall.

I have two ISPs one which is connected to the WAN interface and the other connected to the 5th port on the LAN (LAN port has been assigned to the internet)

My requirement is to give the two servers individual ISP connections.

Server 1 handled by ISP 1 (WAN)

Server 2 handled by ISP 2 (WAN5)

But when I configure this setup (as Load Balancing mode), I have no internet connectivity on ISP 2 (WAN5)

Can anyone help me with this? I have attached screenshots of the relevant scenario.

Did you use tcpdump to determine if the ping went out the right interface?

I have not used tcpdump so far but I did use source ping ( ping -I ) on the second ISP interface.

Since there is no DMZ interface on SMB 1530 I have converted the LAN5 to internet, this LAN5 port once converted turns into WAN5. Therefore I have used the interface name as WAN5 when using source ping.

ping -I WAN5 8.8.8.8

Please confirm with a tcpdump this command is doing what you expect it to.
