For remote server-manager, I usually do this:
* Setup ssh access using public/private keys (password login disabled):
http://wiki.contribs.org/SSH_Public-Private_Keys* Change the port used by SSH in order to reduce log noise about scripts trying to hack into my system:
http://wiki.contribs.org/SSH_Port#Procedure:_SME_7.2* Create an ssh tunnel from my workstation to the SME server for port 443
putty root@aa.bb.cc.dd -P newportnum -i <privatekeyfile> -L 443:localhost:443* run server-manager at localhost -
https://localhost/server-managerHow did you create your port restrictions? Connections to /server-manager are somehow involved with a proxypass directive from localhost to localhost port 980 - so if you created manual port restrictions that might apply to local connections, this might explain why turning them on kills server-manager. Try opening port 980 from localhost to localhost...
