I am using a eco4 security system to monitor my business. At our business we also have wireless internet with a WRT54GS from Linksys. Now obviously the security system has to be hooked into the broadband connection, but the security system and wireless router are not near each other, and I will have to link a cat 5 between them correct? Also on the eco4 what do I put for the IP address, subnet mask and default gateway. is that asking for my my local or public IP address? Thanks for any help.
