This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I'm trying to configure an ipsec ikev2 VPN on my er605, but I'm having great difficulties in configuring it
I state that the pptp and openvpn configurations work correctly
but I need additional ipsec/ikev2 access
I followed the guide described here https://www.tp-link.com/it/support/faq/3447/
but the connection negotiation doesn't even start, I would like to understand where I'm going wrong

Hi @PKD1
Thanks for posting in our business forum.

@Clive_A the result is the same, nothing changes
OK. Just got a confirmation that the Local ID type cannot be matched due to Android does not support the Remote ID type. When you put the ER605 behind the NAT, the Local ID type would be the IP address and this cannot be modified. This will make the authentication fail.
iOS supports changing Remote ID type and it does not happen to Apple products.
Temporary fix now: change it to bridge mode on your modem router. Don't DMZ or put the ER605 behind the NAT.

Hi @PKD1
Thanks for posting in our business forum.
Please share your screenshots step-by-step. Mosaic partial public IP addresses. I need to make sure you have configured it correctly or not.

these are my screenshots
192.168.2.1 is the ISP router set in DMZ towards ER-605
if I use the following settings and try to use ipsec-IKEv2 it still doesn't work

You should port forward before making a VPN connection.
IPsec uses UDP 500 and 4500. You should make sure you have DMZ correctly. If you want, show me the pic of the DMZ on your ISP router.
Does your ISP router get a public IP? Like I said earlier, screenshot with mosaic. I need to see your IP on the WAN status on your ISP router.
(Also, I need both sides' IPsec config. Only reading one site does not rule out the possibility of your misconfig. Or take the responsibility yourself and do the check. I'll finish my part solely.)
If this is not resolved, I need you to Wireshark so to find which phase fails to build up a tunnel.

It seems to be a problem with the Android. At least in my test environment, I did this before. Nothing wrong with it.
You can try to set up an OVPN and try with a computer or other devices to verify if the double-NAT issue is resolved or not by DMZ. If any other types don't work, it seems to be a problem with the NAT.
But if it works, it means NAT is not the case. I need you to Wireshark and work with me to find out which phase fails. This Wireshark should be done on the WAN to capture any incoming ISAKMP. See if the negotiation of phases 1 and 2 can succeed.

@Clive_A these are wireshark logs, I don't understand why port traffic 500 steps to port 40754,
however it does not pass the key exchange

Hi @PKD1
Thanks for posting in our business forum.
Are you trying this out in the LAN?
Can you use the cellular and get a public IP on your cellphone and try to connect to the 188.x.y.z IPsec server?
