What is acSysIPSecSPDProposal3Authentication?

This OID sets the fourth and final message authentication algorithm proposal, acting as the last-resort integrity check method during IPsec tunnel setup. This final option ensures the device can still negotiate tunnels with very old or nonstandard IPsec implementations. Setting Proposal 3 to the most permissive authentication available guarantees a fallback even if all stronger proposals are incompatible.
