Openwrt 19.x split tunnel?

I have a wireguard tunnel to a VPN provider. All my traffic 192.168.10.0 and my wlan guest network 192.168.11.0 is routing over the wireguard tunnel ( wg0 ). Is it possible to exclude an lokal ip adresse, like 192.168.10.241 to route it directly to the internet and not over the tunnel interface wg0?

You can use policy based routing for this.

However, it should be stated in no uncertain terms that 19.07 is EOL and unsupported and has been for several years already. It has many known security vulnerabilities and should not be used anymore. You should look to upgrade ASAP. If your hardware is supported in 23.05, you should upgrade now. Otherwise, consider new hardware.

I need openWRT 19.x in the moment, coz its the only version that supported luks for mips32.

Well maybe, but 19.07 is “before wirguard was even invented and stable in kernel which happened in 2020” and wg in 19.07 is only a prototype and will never ever get upgraded. So if it doesn’t work for you it is your problem to solve since the sourcecode it open to use on github.
