I am running a standalone Cisco router as my tunnel end point for my network. I'm currently still running with the 1280 MTU on the site and running " ipv6 mtu 1280" on the interface my router passes v6 to my network on to keep DF / MSS from being an issue. My question - can the tunnel broker support a larger MTU without difficulity? I see I can set it higher, and I can match that in my router, but I would like some feedback about this first before I jump off. Basically, is the MTU max I can set on the webpage for my tunnel -really- supported with no problems on a Cisco endpoint? Thanks in advance, Dave Anderson www.aprsfl.net
