Model: TL-R480T+  
Hardware Version:
Firmware Version:

I have the above device connected with a static IP address to isp,behind the tp link  i have two firewall devices are connected.  One of the firewalls needs to be connected using s2s vpn to a remote firewall.  But there is a problem with the connection between them (if I connect directly it's works).  I would be happy for yours help what I need to config in order to make the connection between the two firewalls work

 

thanks

  @Pro8613 Hi, I had a similar system before(not in use now), just the model difference. I had two R600VPN set up site2site IPSec VPN(like your firewwall), and they are both behind ISP modem router.

So that was my connection:

R600VPN--Site A Modem Router--Internet--Site B Modem Router--R600VPN

 

There are two things you may need to concern:

1. Open ports 500\4500 for firewall WAN IP address. ( I did port forwarding on ISP modem router)

 

2. On Site A R600VPN, I choose the Aggressive Mode as Exchange Mode.

 

I do not use that R600VPN anymore so I find a screenshot from tplink FAQ:
