To maintain my PCI compliance I am not allowed to have any holes in the firewall of my router. One option is that I only allow outside access to my network by specific IP addresses but this doesn't help since IPhones apparently have dynamic IP addresses. The only options I have come up with is getting another DSL line at the wash or getting a smartphone that will allow static IP addresses and a new router that will allow me to allow access by specific computers. Has anyone found a better way around this.
