Issue

You may run into a problem where a steelhead running 8.0.3a that is configured for Policy-Based Routing will not peer with other Steelheads. The Steelhead will present all traffic as pass-through as asymmetric routing (intentional pass-through) when there is no asymmetry in the network. To further diagnose, you will not only see asymmetric traffic in the "Reports › Networking › Current Connections", but on the "Reports › Diagnostics › Alarm Status", you never see asymmetric routing reported which is a conflict to the current connections.

Solution

To verify you are experiencing this issue, take packet captures on both sides of the WAN to see if the traffic is leaving the network and being received on the remote Steelhead. If you don't see the traffic leaving the server side, then there is a good chance you are running into this issue. To test connectivity from the steelhead perspective, please issue a telnet to the server side from in-path to in-path on port 7800 as seen below.

telnet –b <Local Steelhead> <Peer Steelhead(SH) inpath> 7800

If you are able to connect on 7800 then layer 3 connectivity is there and there should be no reason (per steelhead configuration) that peering should be unavailable as long as no fixed target rules or peering rules are causing the issue. 

As a side note, please check to make sure that no internal/onboard optimization cards that are inside the routers are trying to optimize this traffic and no ACL's are intercepting this traffic sending it elsewhere (possibly PBR).
