Ok, all that blocked traffic you're seeing is TCP flagged traffic that is out of state. It's either blocked because the states have already closed, probably the case on that :PA traffic, ot because the states were never opened, usually due to rouet asymmetry.

You should be trying to find out why that is happening not just trying to pass the traffic anyway. Remove any floating rules you added there. You should not be seeing asymmetric traffic if this is setup correctly.
I assume pings work fine from the policy routed clients?
If you run a packet capture do you see both requests and replies at all points in the path?
