Windows Firewall, trouble opening ports
Posted on 2014-04-18
I have Backup software accessing to a remote computer. set up is like this.
ip address: 10.0.0.10
ip address: 10.0.0.20
Now the backup software was not able to connect to computer B. After enough testing, it was firewall issue on computer B. If I turned off firewall for Domain profile, the software on A is able to connect to B.
Now after I tried to make same windows firewall inbound rules in B like other computers in network which A doesn't have problem connecting to, I didn't find any difference of inbound rules. Weird... So what I did is, I created a manual rule 'Connection from Computer A', then allow all programs, services, any port, any protocol, then add Computer A's IP address to 'Remote IP' and selected 'Any Local IP' in Computer B. This should allow all connections from Computer A to B. But this didn't work.
There's no any block rules on Computer B, all rules are for allow, so there is no overwrapped rules.
I specifically have to turn off windows firewall for Domain profile in order to make the software from computer A to B. What am I doing wrong?
