Hi folks, I know this has come up before, but I'm still having a lot of trouble.

Our office has a SonicWall TZ170 with Enhanded OS, which permits setting up a DMZ on the extra OPT port.

I've got my IPRC set up with one of the public IP's in the same range as teh WAN's public IP. IPRC's gateway is set to use the WAN's gateway.

I can't for the life of me get this thing to work. I have the DMZ set up in "transparent" mode, pointing to the IPRC's public address. But I still can't connect or ping the IPRC. Any ideas?

Thanks!
Lev.

Finally figured it out myself - the router didn't like me defining the public IP address for the DMZ beforehand, but it worked when I defined the address when defining the DMZ's interface.

I have the same setup, just got it working about a month ago after and on and off battle since july.

All i did was create an address object to be the public IP i wanted, and then i put the DMZ in transparent mode and selected that object for my IP.

I also had to get a 2nd IPRC, as I have 3 branch offices connecting on Site to Site VPns that access it via an internal IP, and since you can't use NAT this 2nd card was needed to make IP phones work from offsite (w/o a VPN).


Make sure you change the default pw on the IPRC.

You may want to look into QoS too.. depending on when you got the phones they may or may not have the functionality, if you upgrade the firmware they will. Then you just go to your wan properties in the advanced tab on the sonicwall and check Enable 802.1p tagging. And on your access rules in the firewall page change the QoS properties to preserve from none.

This will at least be doing your best effort to use QoS... even if it gets lost in translation sometimes...

P.S. if you need the firmware PM me.

Help me Obi-Wan Kenobi, you're my only hope. . .

Sonicwall TZ-170 w/ Enhanced OS *CHECK
Inter-Tel 5000 Server with two IPRC cards with ethernet cable plugged into OPT port on Sonicwall *CHECK
OPT Interface set to DMZ Transparent Mode pointing transparent range at one of the public IPs of the IPRC cards *CHECK

Additional information:
IP of OPT interface is the same as the WAN Interface

Pings to IPRC public IP address fail.

Anyone got any ideas? Additional NAT settings? Is there anything I missed?

Thanks in advance. Your help is appreciated.

Do you have an access rule set in the firewall tab?
Should be DMZ -> LAN Source(Any), Destination (IPRC Public Address), Service (Any)

Also Lan -> DMZ i have Source (Any) Destination (Any) Service (Any)

Not sure if the 2nd rule is necessary as it has been a while since i set this up but it's in there and mine works!

Let me know how you make out.
