Hi,
We are currently testing Squid 6.2 with WCCP. Running on Ubuntu 20.04.6 LTS with a GRE tunnel to a Cisco 2821.
We are seeing the following errors in the logs:
I have built Squid 4.15 on the same host and using the same config the Cisco is able to see Squid, send traffic, and there are no WCCP errors in the logs.
I have done a diff between the wccp2.cc source in 4.15 and 6.2 and see that there are quite a few changes. In the release notes I see "WCCP: Validate packets better".
Does anyone understand what is causing these errors? Are there any known issues or patches in progress?
Thanks
Callum
