Cannot cURL using 2nd interface in Dual WAN setup

[guspower]

Hi,

I am running opnsense in a dual-wan configuration; both gateways are in a gateway group. I wish to get the public ip address for each WAN but am unable to cURL through the second gateway interface.

# uname -a
FreeBSD hub.local 14.2-RELEASE-p3 FreeBSD 14.2-RELEASE-p3 stable/25.1-n269769-0381600e81a4 SMP amd64

Using the first gateway interface, everything works fine:

Not so with the 2nd gateway interface: it hangs:

... (continues like this)

I did find an old issue listing a similar problem but the solution did not work.

Any help or ideas about how to progress would be much appreciated!
