I’d go with adjusting the MTU of the physical interface too.

FEC might not be necessary here. Focus on MTU adjustments.

Wait, why would adjusting the physical interface MTU matter? Sounds odd.

Definitely adjust the MTU of the IPsec interface. That usually helps!

FEC sounds familiar, but I can't recall if it applies to this situation. I feel like it might be more about the MTU settings.

I practiced a similar question where adjusting the MTU on the physical interface resolved a similar problem. Maybe that could work here too?

I'm not entirely sure, but I think enabling DF-bit honoring could also be a solution. It seems relevant to fragmentation issues.

I remember we discussed MTU issues in class, so adjusting the MTU of the IPsec interface might help with those error counters.
