18.7 Legacy Series / *SOLVED* (upgrading). IPsec mobile clients with DH2 (modp1024) can't connect.

Privet everybody,

Android clients support DH2 (modp1024) and not support DH14(2048).

in OPNsense web settings: VPN: IPsec: Tunnel Settings for VPN:  DH key group = 2(1024 bits)

but in IPsec log:

Dec 13 15:10:05    charon: 16[IKE] <146> negotiated DH group not supported

How to enable DH2 support?

OPNsense 18.7.4-amd64
