I started getting ssh client_loop: send disconnect: Broken pipe on ipv6 after some inactivity time on ssh after my ISP switched to ipv6.
While on ipv4, I could ssh to any server and the connection would keep alive with the default configs.
I tried to set ServerAliveInterval 60 in the client and it improved a bit, but I'm still getting disconnected after some hours. The target server/sshd is with the default config.
With the ssh verbose enabled, I get all keeplive packets every 60 seconds as follows:
debug3: send packet: type 80
debug3: receive packet: type 82
debug3: send packet: type 80
debug3: receive packet: type 82
I'm not sure if this is related, but I have bridge connection between my ISP modem and my Asus RT-AC3200 Router. My ipv6 connection type in my router is set to Native
Any ideas what it could be?
