Teamviewer on SG300-52 52-Port

[mahmoud.shedid]

I have an urgent issue with the SG300-52 switch:

- I have a connection on IP 172.16.0.64, Subnet 255.255.255.244 - this is on the VLAN1,
- And a connection on IP 172.16.0.128, Subnet 255.255.255.244 - this is on the VLAN2,
- And I have set the switch to Layer 3.

How could I set a connection between PC1 in VLAN1 and other PC2 in VLAN2 over Teamviewer ? without any others traffic like sharing folders.

Thanks,,

Shedid

Do you mean 255.255.255.224 ? Teamviewer should be worked if both subnet able to access the internet.

Thanks bobhtut1 for your interesting,

But Teamviewer is working over network without internet.

I just set Incoming LAN connections to accept from Extras -> Options ->Generals -> Network settings.

All I want is close all traffic between two different PCs on two VLANs except Teamviewer.

Thanks,,

A defined access-list will help (across VLANs) allowing teamviewer ports (http or https?) and preventing all other traffic.

PS: Why are you using Teamviewer to remote access your LAN? If those are windows devices, then use remote desktop connection, it's less complicated than setting up TeamViewer

Anyway, you should create an access list in the following order

ACL1:
Source: Any
Desti: Any
Allowed Ports: 5938/TCP
Action: Permit

ACL2: 
Source: Any
Desti: Any
Allowed Ports:
Action: Deny

NOTE:
1. ACL2 is optional due to implicit deny, the purpose of ACL2 is just to monitor the hits :)
2. See Teamviewer docs regarding the port: LINK

Dear LJ Gabrillo

You are right about remote desktop connection !! :)
Can I use same both ACL in remote desktop connection.
Because I have test it like below, but can't connect between hosts :(

ACL1:
Source: Any
Desti: Any
Allowed Protocol: RDP
Action: Permit

ACL2: 
Source: Any
Desti: Any
Allowed Ports:
Action: Deny

Thanks,,

[LJ Gabrillo]

What interface did you apply the settings?
Also, it's

ACL1:
Source: Any
Desti: Any
Source Port: Any
Destination Port: Windows RDP(3389/TCP and 3389/UDP) 
Action: Permit

ACL2: 
Source: Any
Desti: Any
Protocol/s(Source & Desti): Any
Action: Deny

Try to check your ACL hits as well, make sure to use extended ACL

Dear LJ Gabrillo

I have tested that, and nothing to change.

The Attachement is the result for this command. run show
