 |
I know there are tons of threads on port forwarding issues and getting them to work. I thought I had fixed the issue, but now it seems to be something slightly different.
Firmware: DD-WRT v24-sp2 (03/25/13) std - build 21061
Router: Buffalo WZR-HP-G300NH2
Currently, to test out, I have my firewall completely off. I also have this command running:
| Quote: | insmod ipt_mark
insmod xt_mark
iptables -t mangle -A PREROUTING -i ! `get_wanface` -d `nvram get wan_ipaddr` -j MARK --set-mark 0xd001
iptables -t mangle -A PREROUTING -j CONNMARK --save-mark
iptables -t nat -A POSTROUTING -m mark --mark 0xd001 -j MASQUERADE |
I have two ports that are actually forwarding, one is my Plex server 32400 and the other is RDP, 3389. Those are showing open. Although I'm not able to access my Plex server outside of my network even though it's showing open. My RDP is working correctly though. I'm able to access from anywhere.
I tried to open a few more ports, but even though I did the same process, they aren't open. I tested with port 1900 and a random higher port and neither will open.
