You are free to set it to the size of your choice.

However, HE should let us have another setting:  Simply set it to the jumbo packet size of 9,000 (HE's maximum) and let PMTU size it....

I noticed that default MTU for tunnel is 1480, this value is ok if connection with Internet has MTU = 1500. In my country Internet providers like to use L2TP or PPPoE to provide internet connection. Because of that default MTU for internet connection is reduced (for example to to 1460 in L2TP case). And because of that my tunnel connection didn't work until I changed tunnel MTU settings.

I propose to change default MTU to 1280 (minimal possible MTU size in ipv6) or move MTU setting on `IPv6 Tunnel` tab and  instruct users how to find their MTU.

I have pretty old tunnel, which was likely created before HE started blocking IRC and SMTP - it was created on 20th of Feb 2012. I don't have any controls there and as far as I remember HE didn't enforce blocking rules on tunnels which were created prior to block introduction.

I also have tunnel created Dec last year. Advanced tab in this tunnel configuration has options to unblock IRC and SMTP.

Traffic is not reaching my tunnel endpoint. To the best of my abilities, I'm suspecting routing problems on HE side.

Data I gathered so far:
 - Ping from ::2 client endpoint to ::1 server endpoint works (which proves that IPv4 transport works as expected in both directions).
 - Ping from ::2 client endpoint to a tunnel on tserv5.lon1 delivers ICMPv6 packet to destination, but the reply doesn't reach me.
 - Ping from ::2 client to non-HE ipv6 address behaves in the same way: requests go out, responses never return.
 - There's no ingress traffic on the tunnel apart from ICMPv6 replies from ::1 server endpoint when pinged. I'd expect at least DNS and SMTP chatter.
 - HE traceroute6 from stops at 2nd hop (> traceroute ipv6 2001:470:....::2  source 2001:470:0:23c::1 numeric)
 - HE traceroute6 from within reaches stalls at 7th hop, nothing reaches my client (> traceroute ipv6 2001:470:....::2  source 2001:470:0:2a::1 numeric)

My naive guess would be that tserv6.fra1 is not announcing locally connected networks.

Did you create a tunnel then go to Advanced under Tunnel Details?
