need help with opnsense setup

[skullcmd]

not very strong with networking, had a friend setup opnsense on my previous server but i need to reset it up on the new server and changing wan on opnsense to the new public ip and gateway isnt doing the trick.

previous/host interface file

iface lo inet loopback
iface ens18 inet manual
auto wanbr0
iface wanbr0 inet6 static
address 2a0e:97c0:3ea:f1::34/64
gateway fe80::1
bridge-ports ens18
bridge-stp off
bridge-fd 0
mtu 65520
auto vmbr0
iface vmbr0 inet static
address 192.168.1.2/24
gateway 192.168.1.1
bridge-ports none
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094
mtu 65520
#opnsense LAN
auto vmbr1
iface vmbri inet static
address 192.168.38.2/24
bridge-ports none
bridge-stp off
bridge-fd 0
mtu 65520
#For things that need a high MTU


i have the opnsense configuration, i simply changed the gateway interface and wan address, i also used the ui and no luck. i also dont know how to hook up opnsense to a vlan so i can use the gui, currently using masquerading and i just have wan holding the public ipv4 and bridging the network device with vmbr being used for vms/cts. ive checked network config on the vm itself to make sure its hooked up correctly to the right interfaces
