My understanding is your router is on the same subnet as rl0, what is the address of your router, this should be the same as your default gateway or "mygate".

Then you rl0 subnet address range must include this gateway address.

So let's just sort out rl0, make sure you can ping the router and the router replies. The next step is confirm you can ping an address beyond the router.

You may want to set up /etc/resolv.conf so that either

(a) you use a name server beyond the router

(b) you use the router as the nameserver itself as long as it does DNS proxy.
