Region : UnitedStates

Model : TL-R600VPN

Hardware Version : V2

Firmware Version : 1.2.2

ISP : Cablevision & FIOS


I have 3 TL-R600VPN routers. 1 at the main office. The other 2 at remotes sites. Each remote site has 1 pc. These remote PCs are to connect to server in main office.

All 3 sites have Dynamic DNS & we have setup properly with Dyndns to translate the Domain names.

Main office is set up locally with address range 192.168.1.x
Remote Office1 is setup locally with address range 192.168.2.x
Remote Office2 is setup locally with address range 192.168.3.x

IKE Policy:
Mode: Agrressive
ID Type: IP
MD5 3DES DH2
SA Lifetime: 28800
DPD: 10 seconds

IPsec Policy:
Remote Gateway: Domain Name
Mode: IKE
Security Protocol: ESP
Authentication Algorithm: MD5
Encryption Algorithm: 3DES
PFS Group: NONE
Lifetime: 28800
Status: Enabled

I setup separate IKE & IPsec for each connection.

Problem: Only Remote Office1 establishes a connection to Main Office. Remote Office2 does not establish an SA.

Remote Office2 log:
