I have ASA5510 and i blocked all traffic from accessing to internet. Now I want only teamviewer to access to internet.

How Can I do that??

Hi albosaery,

please try to make an access rule on your firewall ruleset to allow:
- Source (any or your client network)
- Destination any
- Service/Port: TCP 5938
This port is used by teamviewer.

Pay attention that this permit rule is over/before the deny rule which you made to deny the access to the internet.

Sorry, I tried to open this

Hi,

Please take captures on your Outside interface and see what port traffic you are receiving on ASA and accordingly you can open the port.

Also if you are using 8.3+ version that your destination in the ACL for inbound traffic would be the Real IP.

Hope it helps.
