DD-WRT blocking one port

post #1 of 20
Thread Starter 
I have DD-WRT running on a Linksys WRT54G V3. It's blocking one of my ports: 16270. I'm trying to connect to a Ventrilo channel. I can connect to other channels, and I can connect to it if I remove the router from the equation, but I cannot, for the life of me, convince it to open that port.

I've tried port forwarding, port range forwarding, port triggering, and the DMZ. I've tried combinations of them, and I've tried them on their own. I've disabled the SPI firewall. I've enabled and disabled UPnP. Nothing works. It can't be my computer, because it works when I take the router out, but the router isn't blocking everything, because it doesn't block my games or any other Vent channels. I had it running the 13064 standard generic firmware, and I've upgraded it to the 14896 standard generic. I've retried all of the previous steps. Nothing works.

It's probably obvious, but I can't ping the Vent server I'm trying to connect to, even with the direct IP. Well, I can ping it, but I get no response.

Does anyone have any ideas?

You don't need to port forward to originate a connection from the inside of PAT to the outside of PAT..

if that port doesn't work then just use a different port. why do you need to use that particular port?
there are over 64k ports to choose from. why that one?

So what should I do instead? Like I said, as far as I can tell, the problem is occurring because of my router, and it's specific to that one server.

Because that's the one the server administrator chose? I am not hosting the server, and you have to connect to the port the server is using.

Whats the server?
Are you sure it is your router, because like beers said, the connection should recognize that you are initiating the outbound connection and allow it to pass through.

If it was an incoming connection then there might be a problem.

Like I said, if I plug my computer straight into my internet connection, I can connect to the server. If I use a different router, I can connect to the server (I do not wish to use the other router, so do not suggest I switch to it). The only time I can't connect to the server is with this router plugged in. Therefore, I am convinced that the router is the problem.

It's Ryman's Vent that I can't connect to. Like I said, I've connected before, and there were people in it at the time.

Try re-flashing DD-WRT on it.

I did last night, with the newer firmware. It didn't solve the issue.

Er, no need to reflash, but I definitely would "factory" reset the router.

Yeah, I've done that as well, but when it didn't solve the problem, I reflashed it.

Does anyone have any ideas about what could actually be blocking that port or IP? The advice so far has basically been to reset the router, but that only works if there's something going on in the router that's preventing the signal from going through. So what could do that?
