>hub RS232 IP=192.168.10.1/31 (Amiga=192.168.10.11)
>hub LocalLan IP=192.168.16.1/24
If it's a real hub with the RS232 bridged in (same segment/collision domain) this may be the first problem: you'll have to use the same network address / mask on all ports incl. RS232. 'IP=192.168.10.1/31 (Amiga=192.168.10.11)' is a contradiction in itself and a CIDR mask of /31 is absolutely senseless: there one bit left for the host part, but the host part must not be all 0s or all 1s, so there's nothing left... And a hub usually has no IP (only managed ones).
>ruter2 LocalLan IP=192.168.16.2/24
>ruter2 Wifi IP=10.0.1.200/24
OK.
>ruter1 Wifi IP=10.0.1.1/24
>ruter1->Internet
This looks OK, but all hosts/routers must be aware of the segments available. The Amiga should have a default gateway of 192.168.16.2 and the packets find their way out. But router1 doesn't know about the 192.168.16/24 segment and the answer packets can't find their way back. You'll have to add a static route for router1 192.168.16.0/24 -> 10.0.1.200 to enable traffic between it and the Amiga. Plus router2 has to have a default gateway -> 10.0.1.1. to reach the internet.
PS: just read up a bit on what's to be found for the EP-3506: it looks like the serial port is routed, so you'll have to add/modify the routes there, too. (And the segmenting you posted looks OK.)
