When you defined the address of the LTM to the GTM it should use that address. If it has more than one defined, you may be able to do a tcpdump on the possible destinations and see which is getting hit.
tcpdump -ni 0.0 host and port 22Jason
Your question doesn't make a lot of sense. The GTM will use tcp/4353 for iquery. It will source from a GTM source IP to a LTM self IP. It uses port 22 to establish the trust when you run a bigip_add pointed to the LTM (the bigip server object you want to monitor).
