Getting error while trying to add /31 in VSX

I am trying to add /31 prefix in my new VSX environment. Is it a bug or something that VSX doesn't allow ?

 

Same /31 prefix is allowed to add in appliance based checkpoint .

See sk91020 which talks about support for /31 and says this does not apply to VSX

What error do you get? And are you sure fw is already vsx? (vsx on \ vsx off)

Because if you try to add the interface while it is still normal gw I would indeed expect error.

Hi @Lesley , yes the firewall was on VSX mode. Another interface in the same VSX was running fine but looks like /31 is not accepted in VSX environment but is definitely accepted in normal checkpoint appliance environment. We introduced a point-to-point RFC 1918 Private IP and then routed over the public IP using the private IP.
