[tor-relays] Server lost Stable flag but has more than 60 days uptime

[Christoph Graf]

I had a similar problem recently. As I suspected an MTU path discovery 
problem due to filtered ICMP traffic somewhere along the path I started 
to clamp TCP MSS to 1200. Performancewise not exactly great, but I am 
back in business since. Done this way on my raspi:

# iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 
1200
