SOPHOS BACKUP GATEWAY

Hi Ihenock,

Thank you for reaching out to the Community! 

Could you provide more detail about the sites you're trying to access from the external network? How did you publish these sites? Using WAF or DNAT rules?

Do you see traffic from the external public IP on the firewall while accessing the sites? 

Thanks,

I used the DNAT rule it works with the primary Gateway i can access the internal resources however using the backup gateway it is not working

Just to clarify: You published services at your internal sites over DNAT to external world, right?
Are you accessing this services via FQDN from outside your network? Just keep in mind, that your ip is not reachable at the time it fails over to backup gateway and so your A-Record for this fqdn will not be reachable until you switch your a record to the backup external ip.

I am not sure i got your setup tho...
