Routing from private lan to private lan on public wan

[eradicator006]

For the past day I've been trying to get my IPTV boxes working from behind pfsense and not through the provided gateway.  I'm having some troubles.  TV works fine for a few hours then it drops out completely.

My WAN interface goes directly to my ONT and it's a configured as a vlan.  TV and internet use the same vlan.  IGMP proxy is configured and corresponding rules are on the WAN interface.  IPTV boxes are on a separate internal vlan from my main network with it's own dhcp server (configured if pfsense).

Running tcpdump on the vlan interface on pfsense I see this:

09:38:15.927960 IP (tos 0x58, ttl 128, id 482, offset 0, flags [DF], proto TCP (6), length 52)
    172.16.1.65.1046 > 10.37.253.25.443: Flags ~~, cksum 0x69af (correct), seq 14502443, win 65535, options [mss 1458,nop,wscale 2,nop,nop,sackOK], length 0

I'm pretty sure this is for registration.  If my IPTV box doesn't get a reply from the registration server it will not work.  These requests send out ever 5 minutes.

Anyway, my question is; How do I get my IPTV boxes on 172.16.1.0/24 to talk to 10.37.253.25 which is on the WAN?

I'm also seeing this when the IPTV boxes don't work, any idea what it is?
