Hello guys,

I configured an IPsec VPN tunnel between a pocket TPlink MR3020 and a Sophos UTM. The tunnel is UP, appears on both devices, but the traffic is not working.
I investigated on Sophos side and i see the traffic is coming from the TPlink and a reply is being sent back through the tunnel, so the TPlink must be somehow blocking the traffic. Here is an emulator of my TPlink's GUI: https://www.tp-link.com/resources/simulator/MR3020_V3-2-23/index.htm
I have no ideea what to check more in the TPlink, as the menu is pretty limited.
Do you know if there is a NAT-T setting and anti-reply setting in the TPlink somewhere? Could only find DPD, but the other 2 not.

Any ideea would be very helpfull.

Thanks

@panicos  What was finally the root cause? I am having the exact same issue. TP-link MR3020 is dropping UDP packets after the IP Sec tunnel is up. Although I have disabled the SPI firewall and the DoS protection, it is still not replying to any traffic but ECHO requests. Any clue?
