I have a dlink gigabit switch that I've installed DD-WRT v24-sp firmware on to. I'm using the switch purely as a router and have a separate firewall device.
I have my firewall and home computer plugged in to the DD-WRT device but can't ping from the Firewall to the Home computer. Yet from the DD-WRT admin page I can ping my home computer without any problems.
So it looks as though the DD-WRT switch is blocking incoming requests, or LAN->LAN requests from devices. I've disabled the firewall completely and checked nearly every option in the web interface and nothing is making a difference.
Any suggestions?
