Load balancer won't forward port 9090 (but works for TCP 80)

[ryantang]

I'm trying to load balance two servers that are running services on port 80 and 9090. I've created two tcp_l4 virtual clusters: one for each port. Strangely, the one for port 80 appears to be forwarding traffic okay, but port 9090 does not. I'm running equalizer version 7.2.1d, platform e350si.

Both have the same cluster IP (172.16.16.40), and the same servers within the clusters (10.100.10.26 and 10.100.10.26). The only difference between the virtual clusters is the port and the cluster name.

When I run a packet capture on the hosts, I see TCP probes sent to port 9090 from the equalizer. However, connections from my browser to 172.16.16.40:9090, it times out. No packets seem to be forwarded either (but the probes still continue). Port 9090 works when I connect directly to 10.100.10.26:9090 or 10.100.10.27:9090.

A packet capture on port 80 shows both the probes and traffic being forwarded.

Any suggestions? Is this likely a mis-configuration? Or did I hit upon a bug?

Thanks!

Hi and thanks for the question,

This works perfectly. I have it running on an E450GX running 8.6.0a in layer 4 and layer 7 with spoofing on and spoofing off. The traffic I'm serving on port 9090 is HTTP.
