ClassLink's Reverse Proxy service allows users the ability to access internal apps (websites) from any external network through LaunchPad. The setup of a Reverse Proxy requires the configuration of a dedicated server, with a series of precise requirements needed for the proxied apps to function properly.
Minimum Requirements - Virtual or Physical
- CPU: At least 2vCPUs VM; 2.0 GHz 64-bit (x64)
- RAM: At least 4 GB Minimum
- HDD: At least 20 GB free space
Operating System: Linux (CentOS 7: Basic Web Server is required)
- Public IP Address mapped to the server's internal IP over ports 443 and 3000
- External and Internal DNS Record
- A DNS "A" record must be assigned to the webserver on a public DNS provider (pointing to the external IP address of the server) and on the internal DNS (pointing to the internal IP address of the server).
- SSL certificate
- The certificate, key, and chain files MUST all be provided.
Note: A wildcard certificate is mandatory for the server to function properly.
|Outside to DMZ||Any||Reverse Proxy Server||443 & 3000|
|DMZ to Inside||Reverse Proxy Server||Target internal IP addresses of sites being proxied||The ports the target sites are listening on; varies depending on the web app (most will be 443 or 80)|
- Each application requires both an internal and external DNS entry.
- The first application can use the server's A record.
- All subsequent applications need a CNAME record pointing to the A record.
- Firewall communications must be allowed between the reverse proxy server and the application server.
