SONICWALL SOHO3 NAT ENABLED HELP!

Hi everyone,

I would appreciate if someone could help me out configuring NAT with SonicWall Soho3. It's becoming a real pain....

We have 20 computers, 2 servers, 2 routers and un SonicWall Soho3 firewall in our LAN. When I configure the SonicWall in Standard Mode it works fine.

The problem arises when I try to configure it to NAT ENABLED.

NAT ENABLED

SONICWALL LAN IP - 192.168.XX.XXX
SUBNET MASK - 255.255.255.0

WAN GATEWAY ROUTER - XX.XX.XX.2
SONIC WALL WAN IP (NAT PUBLIC) - XX.XX.XX.28

--- the last two provided by the ISP

DNS SERVER 1 - 194.XX.XX.XX
DNS SERVER 2 - 194.XX.XX.XX

I cannot still figure out what's going wrong. Have checked a thousand times with our ISP to see if the Public IP and the WAN Gateway are correct, and so they seem they are....

The only things I can get from the Soho Log are the following lines.... maybe they help:

Web access request received 192.168.xx.xx, 3327, LAN (admin) 192.168.xx.xx, 80 LAN Web (HTTP)

… and right after ….

ARP timeout 0.0.0.0 xx.xx.xx.2 - the wan gateway address

Thanks in advance,
chisco

Did you set up One-One NAT in the Advanced section?
You may have inadvertenly set up your SONICWALL WAN IP (NAT PUBLIC) in the On-One NAT Section..

The solution was the following:

The main problem was a router misconfiguration. I was having it the Single User Account option to YES instead of NO.

So the first thing I did was to configure the router setting the Single User Account option to NO and calculate the router LAN IP address (mask add 1). At first it sounded weird since I'm having more than one computer connected to the internet, although it seems that the firewall takes in charge to allow more than one computer to connect to the internet even if the router Single User Account option is set to YES.

Then, went into the firewall and placed the following parameters:

NAT ENABLED

SONICWALL LAN IP - 192.168.XX.XXX
SUBNET MASK - 255.255.255.0

WAN GATEWAY ROUTER - XX.XX.XX.1 - calculated (mask add 1)
SONIC WALL WAN IP (NAT PUBLIC) - XX.XX.XX.28 - given by the isp

Each computer gateway was set to the SONICWALL LAN IP. After it worked everything as supposed.

The solution jreng was giving, this is, setting the firewall Advanced Options One-to-One NAT it is only needed if you are having more than one IP Public addresses.

thanks,
