Now there’s an attention grabbing headline if ever I saw one!
Just a quick reminder post in case I come across this again or it helps anyone else.
We did some work for a client recently to replace their firewall with a shiny new Sonicwall NSA 2600.
In the days following the replacement we were getting reports of connectivity problems.
Inbound connections to the remote desktop server were dropping out and a web application they use was suffering from time outs.
Even pings out to various servers on the internet were giving us results that showed something wasn’t quite right.
The only thing that had changed was the firewall so we put the old one back in and everything returned to normal.
This meant I spent a few hours going through each setting. We’d set the new firewall up exactly the same as the old one but there was clearly that mentions this setting.
The scenario discussed in the article doesn’t fit our setup though.
We weren’t using load balancing, both connections had a different default gateway and traffic was flowing across both connections, just not very well.
However, changing the setting worked. Turning it back off caused the issue to reoccur.
It’s been fine now for almost a month,

Hi Andy,
We did the same fix but when we moved to 6.2.5 we are again experiencing the same problem before.
Have you tried the latest firmware?
Hi Nap,
Haven’t upgraded that firewall to 6.2.5 just yet
Will take a look
Thanks
Andy
Hi Nap
Upgraded to 6.2.6 this week (eventually! Needed to organise with the customer)
It’s been a few days and we’ve had no problems so far
