Re: [44net] Yahoo.com hangs via 44Net

Hi all, I’m having an issue with my 44Net tunnel. It works beautifully incoming and almost as good outgoing. For some reason, while on a 44Net IP’ed computer, I can’t reach yahoo.com. > All other locations I’ve tried work well and off the 44Net, yahoo.com is reachable.

That kind of problems is usually caused by over-active network admins that block all ICMP and thus kill PMTU discovery. You can work around it by doing "TCP MSS clamping" at your end. E.g. when you have a MikroTik router:

/ip firewall mangle add action=change-mss chain=forward new-mss=clamp-to-pmtu passthrough=yes \ protocol=tcp tcp-flags=syn
