Hello, I am trying to upgrade my squid from 2.5 to 3.1. I have got all my old configuration working on 3.1, except... I am coming across a problem with WCCPv1.
172.16.13.56 is the address of the squid box. 172.16.13.2 is the address of the cisco router. I have wccp_router=172.16.13.2 in my squid.conf. squid-2.5 connects to UDP port 2048, I get replies, and everything else then works. Here is a tcpdump of the initial connection: 16:12:13.404466 IP 172.16.13.56.2048 > 172.16.13.2.2048: UDP, length 52 16:12:13.406764 IP 172.16.13.2.2048 > 172.16.13.56.2048: UDP, length 64 But, squid-3.1 looks like it is trying to connect to UDP port 0 on the cisco. Here is the equivalent tcpdump with squid-3.1: 15:59:10.093415 IP 172.16.13.56.2048 > 172.16.13.2.0: UDP, length 52 15:59:10.094423 IP 172.16.13.2 > 172.16.13.56: ICMP 172.16.13.2 udp port 0 unreachable, length I have looked at the src/wccp.c for squid-2.5, and it is clear that the port is being set to 2048 for the connection to the router. I have also looked at the source for 2.6, 2.7 and 3.0 (src/wccp.cc for this version). In all those, it appears to be setting the port on the outgoing connection. However, in the 3.1 source, it doesn't. Is this a bug? Has anybody got WCCPv1 working with squid-3.1?
