WRT54GL tomato OpenVPN TLS 1.2 supported?

    Hi, I am trying to use tls-version-min 1.2 in my openvpn client config on a WRT54GL router with Tomato tomato-ND-1.28.5x-124-VPN on it. The OpenVPN client cannot connect when I am using that option although my OpenVPN server (also a Tomato on an E4200v1) supports it and I am able to connect other clients (like my laptop) using the same config.

    I tried to install the smallest k26 vpn fw on this router in hope that it would have a newer version of openvpn on it but the smallest is still too large for the 4mb ram that this router has available.

    Is there a way to use tls 1.2 on this device or not? And if there is then what is it?

    Thanks

    From the OpenVPN documentation ...

    So that begs the question, which versions of OpenVPN are running on both sides (openvpn --version)?

    I ran the command on both routers and the result was:
    wrt54gl: 2.3.6
    e4200: 2.3.7

    So I reset the wrt router and re-made all vpn configs using a generated certificate and this time the client started up successfully. I'm not sure why it did not the previous time I tried, some config mistake I assume.

    Thanks for the help, it looks like both devices can use tls 1.2.

    PS: I thought it might be useful to also mention the version of firmware I have on the e4200 router. It is Tomato Firmware 1.28.0000 MIPSR2-132 K26 USB Mega-VPN
