Hi Dale,
You can use packet captures or similar stuff on the remote side to check if it is responding to our requests.
In order to check for filters on the SRX :-
- Identify which interface you have specified as the external-interface in the ike gateway config.
- #show interfaces <name_of_interface>
- Check if you see any filters applied as input/output.
- show interfaces lo0
- Again check for filters on this.
- FIlter config can be checked using "#show firewall" on the SRX.

Sahil Sharma
