Hi everyone, to make a particular ipsec work correctly, I have to manually set the mtu through advanced shell:
iptables -t mangle -I POSTROUTING -d 192.168.15.0/24 -p tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 1300
This way everything works smoothly, the problem is it's not persistent on reboot, is there any way to make this change persistent?
