私は、現在Azureアプリサービスで実行されているAsp.net MVC 4 Webサイトにsage pay支払いゲートウェイを統合しています。そのため、 Sagepayからの応答を取得するには、 Azureアプリ サービスで上記のポートを開く必要があります。これが彼らがするように頼んだことです。
"Please ensure that all of the following IP addresses are allowed within your Server or Firewall:
For outbound traffic to our gateway:
195.170.169.9 – live.sagepay.com
195.170.169.8 – test.sagepay.com
For inbound traffic you only need to whitelist IPs if you are using SERVER as this is the only solution that initiates call backs. You don’t need to apply this for our FORM and DIRECT integrations. The IPs from which we call back are:
195.170.169.14
195.170.169.18
195.170.169.15
The Subnet mask used by Sage Pay is 255.255.255.000
Please ensure that your firewalls allow outbound Port 443 (HTTPS only!) and inbound Ports 443 (and optionally 80 HTTP) access in order to communicate with our servers (on Simulator/Test/Live).
There is however always scope for this to change depending on how we a utilising our data centres servers. Sage Pay own the entire 195.170.169.0/255 range (256 IP’s). If you are happy to allow this range then this automatically accommodates any future changes."
