Thank you everyone for your help. It's making more sense to me now so I'll give it a try! :)

Oh, I see! Must admit I didn't even think this was possible when I read "The size of the original source address range (Source) must be equal to the size of the translated source address range (SNAT)" in the help. So (to confirm I've got my head around this!) the Source is my local subnet (the one I want to 'hide'), the…

Thanks very much @Fred_77 and @PeterUK. I'm sure I read those article previously (I've read so many trying to figure this out that I've lost track!). However, if I've understood it correctly, the 'NATted subnet' and the local subnet have to be the same size (so there's a 1:1 translation between the 'real' IP addresses and…

I have since updated the box' firmware though and the signature updates are now working. So I don't know what the original problem was, but the new firmware seems to…

Thanks @Zyxel_Cooldia for the info. The ZyWall310 is my firewall/NAT so I presume that's going to be fine. Regarding the DNS setup - ao are you saying I need to add an A Record to the DNS settings in the ZyWall 310? If so then how do I find the host name and IP address for the signature server?
