Station mode configuration

The goal is to connect to campground wifi as I travel, i.e.
Public WiFi — Mikrotik Metal 52 ac ---- Pepwave Surf Soho ---- Motorhome wireless clients.
The reason for the Pepwave router vs a Hap is because it is guaranteed to support my Verizon Jetpack Novatel 7730L, and it isn’t listed as supported by Routerboard.

The premise is that I should use some form of station mode to connect the Mikrotik to the campground WiFi.
My immediate problem seems to be that I can’t figure out how to set the default route to the campground WiFi.
Here is what I have tried thus far:
gateway router> public wireless network > Peplink Router > local wireless network

Bridge/Add new/
name=“PublicWifI”
type=Bridge
MTU=1500
arp=enabled
apply/ok<


Add wlan and ether to the bridge group.
Bridge/Ports/add new/
Interface=ether1
Bridge=PublicWiFi
apply/ok
Bridge/Ports/add new/
Interface=wlan1
Bridge=PublicWiFi
apply/ok<

Apply static ip to bridge group. You could use dhcp on this bridge. Because the ether port is assigned to the bridge this will be the ether address.

IP/Addresses/New address=192.168.3.2 (or whatever)
Network 192.168.3.0
Interface=PublicWifi
apply/ok<

Now we connect to the wireless network.

Interfaces
wlan1
scan/start
Click on desired network. Then click “Connect”


For this example the wireless network that we will connect to is a b/g network with a simple password of passw0rd.
First we will create a security profile to use, and then connect to the aforementioned network. Make sure that your authentication method matches that of the public Wifi to which you are connecting.
Wireless/Interfaces/wlan1 (this had better be your only wireless table entry)
Security Profiles
Add new
Name=“ATT_Home” (To test to home ATT Uverse router)
Mode=dynamic keys
Authentication types=WPA PSK, wpa2 psk
Unicast Ciphers=aes ccm
WPA Pre-shared key=90333118304
WPA2 Pre-shared key=90333118304
apply/ok<

Apply the above security profile to the wireless interface:

Wireless
wlan1
security profile=“ATT_Home”
apply/ok<

Any help would be greatly appreciated.
