Question about Barracuda Networks Barracuda Web Filter 410 - firewall Rack-mountable (BYF410A3)

1 Answer

Unit will not resolve DNS

I setup the webfilter. It runs through a Sonicwall firewall. The unit works just fine when its set to a non-active monitoring mode - I can see all traffic in the log... The moment I set it to active, no one can resolve DNS. I have tried internal DNS, External Servers and pointing to the firewall and no luck. I have put in static routes pointing to the internal DNS and a blanket route for all IPs and nothing. I have tried with transparent mode off and on and still same issue. Anyone have any ideas?

Ditch the Barracuda and use the SonicWall Content Filtering option, it's cheaper anyhow.

Barring that, reset it to default, and make sure that it is using the SonicWall as its gateway, along with the proper DNS settings. Also, check for a firmware upgrade on the unit. I've run into a few Barracudas that have nothign in the knowledge base but a firmware upgrade fixes them.

Downlaod tz180 firmware


You need to login to mysonicwall.com to download this firmware. Did you create an account at mysonicwall.com and register this SonicWALL in your account? If you haven't you will need your device serial number and activation code, both of which are printed on the back of your firewall.

I am a admin at a new company and they do not know nor can they find the Admin login and password. Is there a way to hack in to the SonicWALL PRO 230 Firewall unit?


Deafault user: admin
password: password

default ip: 192.168.168.168

if in case you cannot get in, you need to reset the device to its factory default.


thanks

Can not connect to PPPOE DSL


Is there a reason why the Sonicwall needs to do the PPPOE auth? You should be able to let the modem do the PPPOE connection and have the Sonicwall behind it. The Sonic wall will get a private IP address. Andy
