Spidey quiz - why is this tunnel having problems?

[spidey07]

Xanthar gets the cookie for noticing fragmentation problems and suggesting IOS bug.

The real kicker is I have changed IOS versions trying to solve it 4 times. All from the 12.2 line.

Never had a problem before because we're using PIX for all the other tunnel enpoints. Pix uses a MSS of 1360 by default so these fragmentation problems don't arise.

So, as a temp fix can you just lower yours?

This is a great material for my VPN presentation for my IT class, I'm glad that I always read everything in this forum.
Thank you guys, and good luck Spidey.

I'm interested in too if lowering your own MSS can fix it
