I am trying to access my home network, particulary my firewall from outside my home. I have a Motorola SB5100 modem provided by brighthouse and then a GTA GB-250 firewall plugged into that. The firewall is obtaining a DHCP IP from the cable modem. However, from outside my home network, if I type in https://publicIP
, I cannot get to the firewall. I cannot even ping the public IP address. I have verified the IP the firewall is obtaining and I am using the correct one. My guess is the modem is blocking something? Any suggestions on getting through?
