Re: DHCP Server Used for Failover
Just as a thought:
- public DHCP server is at 220.127.116.11, on interface wan1
- internal DHCP server is at 192.168.1.4, on interface internal3
- you are using a default route via wan1; if not, you create a static route to 18.104.22.168 via wan1, gateway is your ISP router
- additionally, you create a link-monitor for wan1, checking that the public server is reachable
- and then you create a second static route to 22.214.171.124, on interface internal3, with a high distance (like 100), gateway 192.168.1.4
- you assign your internal DHCP server a secondary IP address of 126.96.36.199
which will never be used normally because your LAN is different
...yes, wild guessing, but the route link-monitoring is the only mechanism I can think of at the moment. Haven't tried this, that's up to you if you agree.
