Hi guys I need some advice here, I will need to change the ISP from NZ Wireless to Spark in my company. Normally that's easy just simply unplug the old one and plug the new one in the router. But we have a sonicwall firewall, I thought I should ask here for any advice before I actually do anything stupid. Google tell me that I will need to change the external IP address, and DNS in sonicwall, anything else? Any advice is appreciated. Cheers. James
