I recently moved away from wireless Internet at work because it dropped regularly, even without bad weather. The cable modem I switched to has a five IP block, and I installed a SonicWall TZ190. The email does a NAT to the same address as the SonicWall, so when people try to authenticate, they don't see it going to an address other than where it originated. A Web server does a NAT to the address at the far end of the block. Everything works like a dream, but only for about 20 minutes. Then access to the last four IPs drops.
Go there...
