Model: Archer BE3600  
Hardware Version: V1
Firmware Version: 1.2.1 Build 20250804 rel.79639(4555)

WireGuard VPN doesn't have full support for wireguard compatible configurations. When configuration includes both IPv4 and IPv6, my router refuses to add the configuration.

  • Expectation:
  • When importing a wg-quick compatible configuration, I expect the configuration to work without changes.
  • Reality:
  • Some configurations aren't supported.

additional context: removing the IPv6 part from the configuration makes the configuration usable again. when using the wg-quick command on my linux machine, the configuration loads without an issue.

 

VPN Configuration Example (fields have been REDACTED/ALTERED for security):

 

[Interface]
PrivateKey = REDACTED
Address = 13.33.73.11/32, ffff::160d:ffff:77c3:ffde:4/128
DNS = 12.10.0.11, ffff::1

[Peer]
PublicKey = REDACTED
AllowedIPs = 0.0.0.0/0, ::/0
Endpoint = MEGAVPN_URL

Hello @caupatoakosamas ,

Welcome to our community.

 

Currently, only certain TP-Link Wi-Fi Routers support WireGuard VPN.  Wi-Fi Routers Support WireGuard VPN Now.

However, the WireGuard implementation on TP-Link routers may not support all features available in wg-quick, including configurations with both IPv4 and IPv6. This is a known limitation, and removing the IPv6 part is a common workaround.

  @Joseph-TP I see, yes my router supports the WireGuard Client configuration. Is there a plan to support IPv4+IPv6 as well in the future?

Hi,

 

The Archer BE400 V1 is currently the only option from TP-Link for users who urgently need support for IPv6 VPN.

@woozle @Joseph-TP 

i already bought AX10 and the return period is over i just didnt know this was like a limitation that would exist, like it's not like ipv6 is a new thing no. Anyway hopefullythey can add it in future updates, hopefully it's not a technical limitation. Since this is realtek there's no openwrt/ddwrt for my router either.
