Hi guys,

i can't for the life of me get port forwarding to work properly

I need this for utorrent (port 51313), ftp server (port 2121), webserver (8888) and many others

I can't connect to any of these services from outside the lan.

Important things to mention:
1. i have a TP-Link WR-1043ND router with DD-WRT v24-sp2 (06/14/11) std / (SVN revision 17201)
2. i'm connecting to the internet using pppoe and i don't have a home modem or anything else.
3. WAN ip starts with 188.27. ...
4. i am 100% sure i am pointing to the correct ip (192.168.1.100 - static dhcp)
5. WAN port assigment: vlan2
6. the setup is as easy as it gets. connect to the internet using pppoe and give internet access to lan clients. no other routers/switches or anything
7. i used the 30-30-30 reset method before installing dd-wrt
8. MY ISP ISN'T BLOCKING THESE PORTS
9. i've tried connecting with the firewall disabled ... failed
10. i applied the loopback patch

iptables -t nat -A POSTROUTING -m mark --mark 0xd001 -j MASQUERADE

Running DD-WRT v24SP2-MULTI (10/31/11) std - build 17798 on Buffalo WZR-HP-G300NH2, stuck on same issue as previous two submitters. Running one internal web server on port 80, and that responds from outside requests as intended, yet have 3 other internal servers being mapped from other ports (3000, 3001, etc) to local_ip:80, and cannot get any response. Using ShieldsUP these ports showing STEALTH.

Have the same loopback script installed, all forwards showing in iptables/NAT; ISP not blocking. Definitely a noob Rolling Eyes here when comes to ipconfig, but after reading & trying to digest as much as possible, feel like everything is in place...

Try build 15962. Any build after this and port forward doesn't work on my WHR-HP-G300N.

Let me know if this works for you, I am curious if this affects all atheros based buffalo routers.

I was able to resolve forwarding (actually confirmed it was working after I removed other issues in play) on DD-WRT v24SP2-MULTI (10/31/11) std WZR-HP-G300NH2, now have 4 internal devices all providing web content via forwarded ports. See http://www.dd-wrt.com/phpBB2/viewtopic.php?t=149158 for more details.
