I am trying to RDP to my PC over the internet however the connection is timing out because of no response from the remote device.*gasp* Yes, I'm aware this is pretty stupid but this is only a short term thing, in the long term I'll get a VPN set up but I'm happy to accept the risks for now.The router (Asus RT-AC58U) connects directly to the ONT while the PC I am trying to RDP to connected to one of the LAN ports on the router.I have a Gigabit UFB connection with Skinny. To the best of my knowledge Skinny are no longer using CG NAT as the WAN IP of my router is the same IP I get when I enter what's my IP on Google from my PC.I have configured Port Forwading/Destination PAT (WAN address:5555 --> 192.168.1.30:3389) as per below I tested on various port forward checking websites and it's showing the connection as closed/filtered. Troubleshooting done so far :- When an RDP connection is made from an external device on the internet, in this case from a 2degrees 4G connection, from the connection logs I can see on the Asus router, it appears to be allowing the inbound TCP connection as per belowOct 30 18:37:29 kernel: ACCEPT IN=ppp0 OUT=br0 MAC= SRC=118.148.x.x DST=192.168.1.30 LEN=64 TOS=0x00 PREC=0x00 TTL=248 ID=48485 DF PROTO=TCP SPT=11138 DPT=3389 SEQ=728927993 ACK=0 WINDOW=4380 RES=0x00 SYN URGP=0 OPT (020405AC010303030101080AC3B100AB0000000004020000) Oct 30 18:37:32 kernel: ACCEPT IN=ppp0 OUT=br0 MAC= SRC=118.148.x.x DST=192.168.1.30 LEN=64 TOS=0x00 PREC=0x00 TTL=248 ID=2910 DF PROTO=TCP SPT=11138 DPT=3389 SEQ=728927993 ACK=0 WINDOW=4380 RES=0x00 SYN URGP=0 OPT (020405AC010303030101080AC3B10C630000000004020000) Oct 30 18:37:35 kernel: ACCEPT IN=ppp0 OUT=br0 MAC= SRC=118.148.x.x DST=192.168.1.30 LEN=64 TOS=0x00 PREC=0x00 TTL=248 ID=41649 DF PROTO=TCP SPT=11138 DPT=3389 SEQ=728927993 ACK=0 WINDOW=4380 RES=0x00 SYN URGP=0 OPT (020405AC010303030101080AC3B1181B0000000004020000) Oct 30 18:37:38 kernel: ACCEPT IN=ppp0 OUT=br0 MAC= SRC=118.148.x.x DST=192.168.1.30 LEN=48 TOS=0x00 PREC=0x00 TTL=248 ID=50754 DF PROTO=TCP SPT=11138 DPT=3389 SEQ=728927993 ACK=0 WINDOW=4380 RES=0x00 SYN URGP=0 OPT (020405AC04020000) - Turned off Windows Firewall/Defender- Tried using other external ports - 3389, 5150, 7777, etc- Confirmed inbound RDP is enabled on the PC- Confirmed port TCP 3389 on the PC is listening- Ran a Wireshark capture on the PC when making a connection attempt; I do not see any inbound RDP traffic at all From what I gather the inbound traffic is getting past the firewall but for some reason never arrives at the destination. I'd appreciate any advice to troubleshoot this further.
