[squid-users] WCCPV2 with fortigate ERROR: Ignoring WCCPv2 message: truncated record

Fri Jun 24 11:17:18 UTC 2022

Hey David,

I am not sure and can spin up my Forti but from what I remember there are PBR functions in the Forti.
Why would a WCCP be required? To pass only ports 80 and 443 instead of all traffic?

Thanks,
Eliezer

Hi Elizer
No, Fortinet is good.
In this case is connecting HTTP/HTTPs with WCCP from Fortinet to squid did not work, because SQUID refuse to communicate with Fortinet according to "Ignoring WCCPv2 message: truncated record" issue.
With Squid,  Fortinet report that is no WCCP server available.

Hey David,

Just trying to understand something:
Aren’t Fortinet something that should replace squid?
I assumed that it should do a much better job then Squid in many aeras.
What a Fortinet(I have one…) is not covering?

Thanks,
Eliezer

Hi Alex,
is the v5 commit 7a73a54 already included in the latest 5.5,5.6 versions?

This is very unfortunate because WCCP is used by default by Fortinet firewall devices. It should be very popular.
Indeed, Fortinet is flooding the market.
I can volunteer for the funding and the necessary testing to be done.

We trying to using WCCP with Fortigate without success Squid version  5.5 always claim "Ignoring WCCPv2 message: truncated record" 

What can be the cause ? 

The most likely cause are bugs in untested WCCP fixes (v5 commit 7a73a54). Dormant draft PR 970 contains unfinished fixes for the problems in that previous attempt: 
https://github.com/squid-cache/squid/pull/970 

IMHO, folks that need WCCP support should invest into that semi-abandoned Squid feature or risk losing it. WCCP code needs serious refactoring and proper testing. There are currently no Project volunteers that have enough resources and capabilities to do either.

HTH, 

Alex. 

We have added a service ID 80 on fortigate 

config system wccp 
     edit "80" 
         set router-id 10.10.50.1 
         set group-address 0.0.0.0 
         set server-list 10.10.50.2 255.255.255.255 
         set server-type forward 
         set authentication disable 
         set forward-method GRE 
         set return-method GRE 
         set assignment-method HASH 
     next 
end 

Squid wccp configuration 

wccp2_router 10.10.50.1 
wccp_version 3 
# tested v4 do the same behavior 
wccp2_rebuild_wait on 
wccp2_forwarding_method gre 
wccp2_return_method gre 
wccp2_assignment_method hash 
wccp2_service dynamic 80
