Modem - CP - LAN Router - Users.
CP has eth1 attached to Modem.
eth1 has obtain ip automatically, with custom dhcp options configured in dhclient and recieves public IP from ISP.
DHCP for the LAN is done on the CP.
Local traffic via the LAN router routes to the CP and CP hides local traffic behind the public IP assigned to eth1.
eth2 attached to LAN router is static. Fixed 192.168.0.0/24 address
eth1, attached to ISP modem is dynamic (ISP wont give fixed IP)
Gateway is managed locally via eth2. DAIP is NOT enabled as gateway is managed on LAN via static IP.
So, the question is, when the public IP attached to eth1 changes, how do these changes apply to the rest of the process?
How can the topology in SC update automatically? Otherwise, traffic will stop and fail. Traffic will try be hide nat behind the old public IP as topology hasnt updated.
There must be a way for this?
