SNAT Rule not working with WebFilter enabled

Hello Peter, 

Thanks for reaching out to Sophos Community.

Could you show Web Filtering Profile for this traffic? Could you skip transparent mode for the specific host/server in the Web Protection > Filtering Options > Misc > Transparent Mode Skiplist and see if this could help make the traffic pass through.

Hello Raphael,

we are using web filter with transparent mode for this traffic, or which setting do you mean. We already added all destination Hosts/Networks to the Transparent Mode Skiplist (source and destination), but while checking the firewall logs the SNAT Rules are not getting applied.
