Carp Protocol Comedy: When Fish and Firewalls Team Up!
CARP isn’t just a fishy tale from the Middle Ages; it’s a crucial network failover feature. Developed by OpenBSD, CARP ensures seamless IP address handover between firewalls, while PFSYNC keeps them in sync. Just remember, dedicated links are recommended, unless you want your network secrets swimming with the fishes!
Hot Take:
Forget fish on a plate; the real catch of the day is network redundancy with CARP! While monks of yore were busy maximizing their Lent fish intake, modern techies are more concerned with maximizing network uptime. But beware: just like carp, your data might be swimming in dangerous waters if you don’t handle it with care!
Key Points:
- CARP (Common Address Redundancy Protocol) is used for network failover management between firewalls.
- PFSYNC allows primary firewalls to communicate connection state changes with secondary firewalls.
- Dedicated network links are crucial for CARP/PFSYNC to protect sensitive traffic.
- PFSYNC is not natively supported by Wireshark; tcpdump can decode it.
- PFSYNC traffic provides session state details but does not disclose traffic volume.
