My older wifi router only 2.4 and occassional was requiring resets, and has public IP mapped to name and number of ports routed to various machines behind it. Wanted to setup the new one with 2.4/5 setup and running before switching everything over. As you mentioned, incoming traffic on second interface was sending return traffic via first interface and thus http didn't work since it had the 100 metric. So, that machine I switched the connections to interfaces.
