Hi - I was tinkering with my configuration and managed to break my VPN server that I use to access my home network. I exported the two config files and found that the line that made the difference was this:
/ip dhcp-client
add comment="default configuration" dhcp-options=hostname,clientid disabled=no interface=ether1-gateway
which was changed in the broken config to this:
/ip dhcp-client
add comment="default configuration" dhcp-options=clientid,clientid disabled=no interface=ether1-gateway
Restoring the hostname option fixed the VPN.
Would anyone be able to explain exactly WHY this change affected my VPN server? Thanks in advance.
