option name 'PassthroughformyServer'
option src 'wan'
option proto 'tcp'
option src_dport '80'
option dest_ip '192.168.1.100'
option dest_port '80'
option target 'DNAT'
option dest 'lan'
config rule
option src 'wan'
option proto 'tcp'
option dest_port '80'
option target 'ACCEPT'
Note: Proto can be 'tcp' OR 'tcpudp' OR 'udp'

I tried to add this to the wiki, but someone (https://openwrt.org/docs/guide-user/base-system/dhcp_configuration?rev=1596434574) decided to replace my simple solution with an obfuscated one that requires uci commands. So instead, it will remain here. EDIT: I added it back. See how long that lasts...
openvpn
opkg install openvpn-openssl
Contents of /etc/config/openvpn

And your .ovpn in /etc/openvpn/.
