Something missing for RDP to work ...

Dan184
Hi Everyone,

I just received a SG125 on Monday which I've been trying to configure over the last few days.

I have 3 external PPPoE connections that we use for different purposes. First external connection is used for internet browsing. The policies in place are working as expect.

However I have a secondary external connection that I want to use for RDP in our internal network.

I have create a DNAT rule that takes the RDP port and forwards it to the station internally. I also created the policy on the Firewall too.By looking at the live logs I can see that I can reach the station thought RDP external and the problems seems to happen when the station is responding to the request as I don't see anything indicating anything going back to the source.

For eg I see : Remote IP --*> Internal IP to port 3389 works 
Internal IP --*> Remote IP does not show at all 

Please advice ....

    I can confirm the firewalls are off 

    The only log I get is this:
    NAT rule #1 TCP SourceIP:4695→DestinationIP(External):3389 
    [SYN] len=52 ttl=128 tos=0x00 srcmac=XX:XX:XX:XX:XX dstmac=XX:XX:XX:XX:XX

    Nothing else comes after that
