NethServer release 7.2.1511 (beta2):
I have been testing Nethserver in my home office for a while, and so far I love the product. Not so long ago I did a fresh install of version 7 (couldn’t figure out a way to upgrade from 6.8) when it was released and recently after a possible software update I have an issue. I log into some clients VPN’s for remote support, and recently this stopped working. I have never configured firewall rules, I did create some port forwarding for my own VPN which also has stopped working recently.
I did a tail on the firewall log and noticed the following when I try to establish a vpn connection to a client’s MS Server.
Oct 14 19:02:56 mail kernel: Shorewall:net2fw:DROP:IN=ens3 OUT=MAC=52:54:00:c9:4e:d6:e0:91:f5:f9:6d:5e:08:00 SRC=220.127.116.11 (ip changed for security) DST=10.0.0.100 LEN=56 TOS=0x18 PREC=0x00 TTL=115 ID=9816 PROTO=47
I then tried to create a firewall rule, saying accept any source, any destination, any service, and always and the GRE 47 still gets dropped.
Any suggestion as to where to start trouble shooting will be greatly appreciated.
