two PA firewalls and we configured in HA (Active-Passive mode).
We got /28 subnet from ISP for 2 internet lease line links. (Single ISP)
configured links on one firewall with IP 220.127.116.11 on interfacet 4 and 18.104.22.168 on interface 2. With next hope 22.214.171.124
after commit we got interface overlap error.
Is it possible to configure this ?
Seems you can not configure 2 Interfaces which belong to same network.
/28 gives you host range from 126.96.36.199 - 188.8.131.52.
What are you trying accomplish here?
Do you need two links to same ISP for Redundancy?
Overlapping subnets are supported only when each overlapping interface/sub-interface is in a separate virtual router.
@bit_byteAs you are taking two separate internet links, why don't you ask ISP to give different subnets for each link so it will have separate gateways? This way you can configure both links as per your requirements. Not sure about your agreements with ISP side but normally we get separate networks for different internet links unless you have your owned public IP addresses and you have asked ISP to route it the way you want.
