Hi All,
I am using this script - to update my cloudflare DNS. I have 2 wan ports and double natted on both of them 
Ideal solution it to run 2 scripts each updating a DNS with their own WAN IP’s.
I can update the one wan ip however it’s not he wan port I want it’s the default wan address - how can I force it to use the second wan path? I have tried a mangle rule but the IP for api.cloudflare.com keeps changing every time I ping it.
suggestions and recommendations please

# ================================================== #
# $ Mikrotik RouterOS update script for CloudFlare $ #
# ================================================== #
# #
# - You need a CloudFlare account & api key (look under settings), #
# a zone and A record in it #
# - All variables in first section are obvious, #
# except CFid and CFzoneid #
# - Obtain CFzoneid from Cloudflare Dashboard, #
# on Overview tab scroll down #
# To obtain CFid use following command in any unix shell: #
# curl -X GET "https://api.cloudflare.com/client/v4/zones/YOUR_ZONE_ID/dns_records?name=YOUR_DOMAIN" -H "Authorization:Bearer $CFtkn" -H "Content-Type: application/json" | python -mjson.tool
# - You can use my Postman script to get those variables #
# - Enable CFDebug if needed - it'll print some info to logs #
# - Enable CFcloud if you don't get a public IP on interface #
# - Put script under /system scripts giving "read,write,ftp" policy access. #
# For 6.29 and older "test" policy is also needed. #
# - Add script to /system scheduler using it's name in "on-event" #
# - Requires at least RouterOS 6.44beta75 for multiple header support #
