I looked through this thread but did not see where anyone suggested
adding or making sure you had the default forward rules in place.

/ip firewall filter
add chain=forward connection-state=established comment="allow
established connections"
add chain=forward connection-state=related comment="allow related connections"
add chain=forward connection-state=invalid action=drop comment="drop
invalid connections"
