Posted: Tue Aug 13, 2013 18:14 Post subject: Port Forward Issues with 22118 on wndr3700v1 and wndr377v2
Problem 1:
I loaded 22118 on my 2 routers. Tried both routers on the gateway with port forwards and port range forwards, using the GUI. The port forwards show up in the iptables with DROP when not enabled. When enabled, they do not appear at all. Problem same on both routers.
So, I chose to use CLI port forwards in the firewall script.
Using v1 box:
Did a 30-30-30 reset.
Power cycle.
Did another 30-30-03 reset.
Power cycle.
Loaded config and firewall while offline using lan cable.
Deployed as gateway.
Power cycled.
Problem 2:
My firewall port forwards and range forwards seem to work when the source is not from my LAN. SSH to LAN machines using the WAN address:port are blocked.
I have SPA3102 SIP ATA box on the LAN that uses a cloud service to route calls based on a dial plan. Calls using my PSTN line (on my LAN) must be connected via P2P connection. The cloud initiates the PSTN call using the Wan-IP:port but is not able to hand off the connection to the LAN-L1 side. I suspect the issue is related to blocking Lan device attempts to use the Wan-IP:port.
I found a thread regarding broken NAT loopback in prior versions that seemed to have these characteristics. However, the suggested fix of adding code to the firewall did not change the situation. Here's the thread I found:
http://www.dd-wrt.com/phpBB2/viewtopic.php?t=89353
I would appreciate any help. I hope there are either commands to add or an unknown router option I missed.
I've attached a subset of my firewall and resulting iptables/NAT.
I am on the 3.x version of 22118 Mega on Asus RT-N16 and just wanted to say that port forwarding seems to be working fine for me. _________________ Please state what make and model router plus the build number and type of DD-WRT you are using. Screen prints and a network diagram can are also helpful. Before you create a new post, use the search function. Chances are your issue has happened to someone else.
Port forwarding has been working for some time and all recent reports that claimed forwarding was broken turned out to be user errrors.
Try to closely read the advanced help that is displayed on the port forward page.
nomad: ipv6 modules are in big included, should also be in mega ? i can copy them for you if not.
Thanks for the offer, they are not included in mega.
But that doesnt matter at this point, i just discovered i can't make sit tunnels (ioctl: No Such Device) with this firmware so i have to revert back to kong's build anyway (which also doesn't have ipv6 netfilter modules by the way).
router e2000, at higher speeds like downloading from torrents 10MB/s the cpu usage is very high, 'top' show me these
82% [kworker/0:1]
12% [ksoftirqd/0]
cpu temp 54C
and sometimes the router reboots.

If you still have a problem show a screenshot of your port forward gui settings + contents /tmp/.ipt file
Thanks. I will retry the GUI port forwards and send the info, if not working.
I'd appreciate feedback on the second issue of allowing an internal LAN device to utilize the port forward using the WAN ip address:port. I provided an attachment of my firewall and iptables. Thanks!
UPDATE: The port forwards are working. The only thing I can think might have been the issue is configuring this with the router not connected to the wan. When on the wan, the gui forwards create the right entries in iptables.
Still have the issue with LAN-IP -> WAN-IP:port.
UPDATE: Turns out VPN causes the port forwards to stop working from the LAN. Once I turned off VPN, they worked.

Router: WNDR3700v2
Found another problem. I have wireless-1 on both radios and guest on 2.4G radio. When I do "ifconfig ath0 down" or same on ath0.1 or ath1, the DOWN works fine.
The UP command shows it is working on the GUI but the radio does not come up. It works this way on all 3 wireless networks I have defined.

Sorry, it was indeed a user error on my part too. For some reason I had put 0.0.0.0 in the source net field, which of course won't work. Thanks for pointing me to the help link on the port forward page, it made me realize my error!
