Versalink 327

Westell has a funny way of naming things. They call int "Static NAT". Go to the configuration menu, select Service Configuration, then look for Static NAT.

Why would you need to put your voip adapter in DMZ. I just plugged mine into the E1 port and it works fine. Is there an advantage to putting the DMZ in??

Well what I want is IP passthrough,I think. The only firewall setting that allows my VOIP adapter to work is none or low. So IP passthrough would be DMZ, therefore the firewall is off for that item only, my adapter. Right?

Why not just set the firewall to none or to low, if it works then.

Most of the protection the modem provides comes from its use of NAT. You still get that even with the firewall off.

Yes I can do that, but I really would like to figure this out. The 327 is a wierd router.

P8 recommends putting thier DTA into DMZ with ip passthrough.

Found the answer here.»www.westell.co.uk/support/downlo···ough.pdf
All I need to do is create a impossible to crack password so my DTA is hacker safe. But even if they could hack in, all they could do would be to change some of my settings.

Well guess what. Still don't work. Single static ip enabled for the DTA. The manual says firewall rules don't apply to items in SSip. Fire wall set on high,I get a dial tone but no connections can be made. Medium same thing. Still only works on low setting or none.

I would still recommend that you go back to default router settings, and set the firewall to low. It will be simpler, and probably more secure.

Westell has some of the most weirdest modem/router settings I seen. The only place I see the versalink talking about MAC address is under troubleshooting > Status > lan devices and under wireless station What are the chances of westell releasing a firmware upgrade adding a DMZ so you can put all your mac addresses under that?

reply to m2deux
This modem/router is incredible. I just passwword protected my DTA voip adapter and now it dosen't show up in my list of LAN devices. It's DNS address dosen't show up in the router either.

If you give it a fixed IP address, it isn't likely to show up very often.

When you don't give it a fixed address, then it must use DHCP to acquire an address. That's how the router learns of its existence. With a fixed IP assigned, there isn't any way for the router to learn that it is there.

When it is actively exchanging packets (as when handling a VOIP connection) it should show up as an active LAN device. Otherwise the router has no indication that it is present.

That's just it. I haven't given it a fixed IP, it's dynamic through DHCP. It showed up when I didn't use password protection. Now that I have, the router dosen't see it???

If you reboot the 327w while the VOIP device is still running, then the VOIP device may retain its old IP. The reboot caused the 327w to forget what it knew about the VOIP device, and there will be no DHCP transaction to remind it. Eventually the IP lease will expire, and your VOIP box will use DHCP to renew its lease. At that time the westell box will learn that it exists.

On the other hand, if you reboot or power-cycle the VOIP box, with the 327w still running, then that will force a new DHCP request and the 327w should then learn about the VOIP box.

This is pretty much the way things work. It isn't just a 327w quirk. It usually doesn't cause any problems. The only thing you are missing is a pseudo-DNS entry for your VOIP box. I doubt that you need that entry. If you really do need it, then rebooting the VOIP box should fix it.

Thanks. I just need to find a way to put my DTA into DMZ, so it will bypass the firewall. Then I can leave the firewall at high setting for everything else. I know you said that NAT in itself is security, but it bugs me that I just cannot get this to work.
