Importing my .ovpn file into my DDWRT router. Having issues on matching up parameters

Question

I just setup ovpn on my ubuntu server and I generated a .ovpn file as seen below. It works on my desktop using the openVPN client using the file. Now I want to import this into my DDWRT router, but I have to manually pick the parameters as seen below.

I'm stuck as to what I need to put in the DDWRT setting according to my .ovpn file.

As for the tls-cipher, I can't find the setting in DDWRT for TLS-ECDHE-ECDSA-WITH-AES-128-GCM-SHA256. I'm not sure what to pick or do I need to change this on my server side?

Also what do I pick for LZO compression?

And I'm not sure if my keys are going to the correct place as seen below.

What else could I be missing here?

proto udp
remote xxxx 10111
dev tun
sndbuf 393216
rcvbuf 393216

Answer 1

I commented out alot of the options in the ovpn file as seen below. I even turned off the tls-ciphers so I didn't have to deal with it in the advanced options in the openvpn setting in DDWRT. I then made sure it works on my desktop client.

Also I did a test by going into the DDWRT router via telnet. And copied the .ovpn file and ran the openvpn myconf.ovpn command, which verifies that its working:

From there I copied the entire .ovpn file into the advanced options > additional config input box.

It wasn't working at first, but I enabled NAT and it started working!!!!

It should look like this on the status page:

client
proto udp
remote xxx.xxx 10111
dev tun
resolv-retry infinite
nobind
persist-key
persist-tun
remote-cert-tls server
verify-x509-name server_IzA1QdFzHLRFfEoQ name
tun-mtu 1500
auth SHA256
auth-nocache
#cipher AES-128-GCM
#cipher AES-128-CBC
#tls-client
#tls-version-min 1.2
#tls-cipher TLS-ECDHE-ECDSA-WITH-AES-128-GCM-SHA256
#tls-cipher TLS-DHE-RSA-WITH-AES-256-CBC-SHA256
#tls-cipher TLS-DHE-RSA-WITH-AES-128-CBC-SHA
