watchcat: ping responses not acknowledged over mesh network on 25.12.0

Package Name

watchcat

Maintainer

OpenWrt Version

25.12.0-rc5

OpenWrt Target/Subtarget

ipq40xx/generic

Steps to Reproduce

Watchcat is not recognizing ping responses if the ping transverses through a mesh network.

Using the diagnostic tool on the same router, ping responses are coming in normally. When Watchcat pings the same address, Watchcat sees no response. This issue was not present with 25.10.X and prior.

Actual Behaviour

Diagnostic Ping response from 192.168.1.1 to 192.168.1.12 over a mesh:
64 bytes from 192.168.1.12: seq=2 ttl=64 time=1.353 ms

Watchcat Ping response missing from 192.168.1.1 to 192.168.1.12 over a mesh::
watchcat[4123]: Could not reach 192.168.1.12 for 1500. Rebooting after reaching 3600

Confirmation Checklist

• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Start at the watchcat package entry point and compare its ping-response handling between 25.12.0-rc5 and 25.10.X. Reproduce the issue by pinging 192.168.1.12 over the mesh, then verify that watchcat acknowledges the response instead of reporting the host as unreachable.
