I could really use help on Inbound Filters
« on: June 28, 2010, 07:25:50 PM »
My brother and I play a few online games together, and neither game has built-in voice chat, so I installed a Teamspeak server on my machine and we both run the client.  Of course, I have to forward the port to my machine, and that works fine.

However, I don't want to leave the port forwarded if we're not playing, so I wind up activating and deactivating that forwarding rule (and the Ghost Recon one if we're playing that game and I'm hosting) whenever we play.  Unfortunately, that requires a reboot, which kicks my whole house off the router (and hence, the Internet) for 30-35 seconds.  With my old Zyxel router, this reboot lasted just a few seconds, and in fact didn't always kick people off.

So, I thought I'd try Inbound Filters.  But I've had zero luck with them.  I want to limit that rule to just my brother's IP address.  To test it, I've created a rule with a different IP and then had him join - he shouldn't be able to join, but he is.

On the same entry as the Teamspeak rule, I leave the schedule at "Always" and I set the Filter to something, but it seems to make no difference.  I even tried "Deny All" and my brother was still able to connect.

I'd appreciate any suggestions.  Thanks.

I should be more specific.

On the "24 - Port Forwarding Rules" screen, I create a rule for Teamspeak.
http://support.dlink.com/Emulators/dir655/133NA/Gaming.html
Name: Teamspeak
TCP: [blank]
Schedule: Always
IP Address: 192.168.0.101 (my machine, to which I assigned a static IP)
UDP: 9987
Filter: Bogus  (see below)

For the Filter, I'll eventually put in a filter with just my brother's IP address, but first I want to confirm that it blocks out anyone else, so I created a "Bogus" filter with an IP address not his.  This means he should not be able to connect.  I even tried the "Deny All" filter.

On the Inbound Filter page (http://support.dlink.com/Emulators/dir655/133NA/Inbound_Filter.html), I entered the name Bogus and clicked on Enable for the first row, where I put the same bogus address for Start and End, and set the Action to "Allow" and added it.  I confirmed that the Filter was in the "Inbound Filters Rules List" and saved.  I was then able to use this filter in my Port Forwarding.

Now, I did some reading, and it appears that UDP Enpoint Filtering can affect the results, so I've tried setting that to both "Endpoint Independent" and "Address Restricted" - I have not tried "Port and Address Restricted" yet.

Has anyone actually created Inbound Filter rules to protect your port forwarding rules, and can verify it works for you?

Thanks.

First are you trying to access the vent/ts server from an internal or external IP?  Try using the inbound filter on the advanced tab?  You must login to enable/disable firewall, routing, port forwarding stuff.  There's no way around it sorry so yeah you'll have to do that 15-30 second router reboot each time. ;(
