iptables, port forwarding, and access from LAN-side
Nothing like firewall rules to make me feel like a moron. I recently wiped and reinstalled OpenWRT on my WRT54G router. Before the wipe, I had firewall rules which forwarded port 80 to a web server on my home LAN behind the router.
The nice part was that I could access that server both from outside and inside the LAN, using the external WAN IP. I've got scraped RSS feeds and other HTTP accessible bits that I access from my laptop. This laptop travels between work and coffee shop and home. I like being able to subscribe to and point at these things by URLs that don't change.
But now, after the wipe, I've got firewall rules which open the WAN port to the home LAN for access from outside - but not from inside. I've lost the old rules, and the knowledge I had that let me build the rules has since paged out of my brain and been lost to the ether.
I suppose I could try building a VPN to home again - or use some SSH port tunneling - but I'd really like to get this port forwarding working again. Anyone know how this crud works?
