How to accessa huawei hilink web interface through wireguard?

I got a wireguard server with dual wan, one of which is a huawei hilink modem with 192.168.8.1 interface, how do i access the web interface, when im connecting from a wireguard peer, i can access lan and wan (internet) without an issue, but i cant figure out connecting to this modem...

These are my firewall rules for wireguard:

config rule
	option name 'internet'
	option family 'ipv4'
	option dest 'wan'
	list dest_ip '0.0.0.0/0'
	option target 'ACCEPT'
	option src 'wg'
	list proto 'all'
	list src_ip '10.9.0.4'
	list src_ip '10.9.0.5'

config rule
	option name 'wg2lan'
	option family 'ipv4'
	option src 'wg'
	option dest 'lan'
	option target 'ACCEPT'
	list proto 'all'
	list src_ip '10.9.0.5'
	list src_ip '10.9.0.6'

is 192.168.1.x == wan ?

x

This is how the interface looks like, i can access 192.168.8.1 from the local network the server is on, but i cannot acccess it through wireguard from outside, is that what ure asking?
192.168.8.100 is accessible both from lan and wireguard and its just luci.

tried creating another rule like internet rule you posted, but for the wanb interface ?

I got both my wan interfaces in one firewall zone, so this rule applies to both of them i would think, im also using mwan3 if this matters, and the wanb is just a failover, but still i can access the modems interface from lan anytime, and i can ping the modem from the router or lan without an issue, the only issue is, i cannot access it from wg..
