OK, thanks ... it may very well be my ISP, I wasn't expecting it on the tunneled traffic though.
It's unlikely to be an ISP, as most of them don't do deep packet inspection on IPIP traffic. I know I haven't added it to the filter list, and a telnet n1uro.ampr.org 25 gets a connection, so as far as I can see it's still working. - Brian
