I have a pair of Cisco controllers setup as mobility anchor controllers, which will basically initiate EoIP tunnel between them. Recently we have placed a Palo Alto 5250 firewalls between the controllers through virtual wire interfaces. The physical connectivity is as follows
Cisco Controller 1 ----> Palo Alto VWire-IN -------> Palo Alto VWire-Out -----> Cisco Controller 2
The issue is that after placing the Palo Alto firewall , the tunnel between the controllers is not coming up. I have all allowed the traffic in both directions. There is no rule blocking the traffic. Please let me know if anyone had the similar issue.

I would wireshark both ends and look and see if the Palo is manipulating the packets in some way. That's about the only thing I can think of that would be breaking this.
@tac.in makes a really good point; you are allowing the traffic with service and application set to 'any' right? I always assume that in a v-wire configuration that is how the rule is built, however that is sometimes something that people can run into.
Please try changing service from application-defaults to any. The tunnel might be on other ports other than default ports .
