Unable to ping to Secondary ISP IP from Primary ISP IP

URONMAPU — Wed, 27 May 2026 09:47:29 GMT

Hello Everyone,

I'm using two internet connections: a primary ISP and a secondary ISP.

Is there a way to ping the public IP address of the secondary ISP from within the local network?

I would appreciate it if you could share the configuration steps.

Thank you so much!

Only if you have different ISP links in configured in different virtual routers.

If both ISP links are in same virtual router and you ping using ISP1 IP towards ISP2 next hop then this packet will go out from ISP2 link using ISP1 IP.

ISP either drops this (if their filters are set correctly due you spoofing source IP that they did not give you) or will receive it but send reply packet towards ISP1 (causing asymmetric traffic).
