Optimize Firewalls and Proxy Servers
The following tips can be useful when setting up firewalls and proxy servers for optimal use.
Firewalls and NetSuite
A firewall is generally set up to protect your network or computer from unwanted internet traffic. The primary function of a firewall is to let good traffic pass through and block bad traffic. If your company uses a firewall to monitor internet traffic, your network manager may need to modify the firewall to use NetSuite successfully.
If you are experiencing performance issues, pages that load slowly, or frequent time-outs, try accessing NetSuite from a location outside of the firewall. If you determine that the firewall may be a problem, try making the following changes to the firewall:
-
Set up the firewall to allow all traffic to and from www.netsuite.com and any of the applicable URLs found in Understanding NetSuite URLs.
-
Open the following ports:
-
Port 80 for non-secure HTTP pages
-
Port 443 for secure HTTPS pages
-
Port 1708 for SuiteAnalytics Connect access
-
Proxy Servers and NetSuite
You shouldn't access NetSuite using a proxy server, if possible.
When your company uses a proxy server for internet traffic, and you visit a web page from your computer, a request is sent to the proxy server for that page. The proxy server retrieves the page from the internet and forwards the page to your computer. The page may then be cached, or saved, on the proxy server's disk drive for future use. For subsequent requests of the same page, the proxy server may return the cached version of the page stored on its drive instead of accessing a current version of the page from the internet.
Cached pages returned by a proxy server can cause problems when using NetSuite, because you need to view accurate and up-to-date information about your company.
