Added management port exclusion (!, -i, eth0) for data plane protocols in iptable rules. Data plane protocols like BGP, BFD, and VXLAN are restricted to data interfaces only, while management protocols (NTP, SNMP, SSH) retain management port access. This enforces proper traffic segregation between management and data plane.
What is the motivation for this PR?
To enhance security by properly segregating management and data plane traffic through iptable rules in caclmgrd.
How did you do it?
Added exclude_mgmt_port rule (!, -i, eth0)
Applied exclusion to data plane protocols (BGP, BFD, VXLAN)
Preserved management port access for management services (NTP, SNMP, SSH)
Implemented conditional exclusion for other ACL rules based on service type
