How do I configure customized http and https ports for HTTP proxy on the Barracuda NG Firewall?

Solution #00005259 
 
Scope:
This solution replies to:
- NG Firewall firmware versions 4.2.x, 5.0.x, 5.2.x
- netfence firmware versions 4.2.x

 
Symptoms:

In some proxy constellations need a customized port which should be forwarded.

e.g. http://www.intranet.com:81 or https://www.intranet.com:81

 

It's possible to allow this ports via a ACL in the proxy but the proxy does not accept http requests on port 81.


 
Solution:

The squid proxy only accept http / https requests on this ports as default.
  443 563 # https
  80      # http
  21      # ftp
  70      # gopher
  210     # wais
  280     # http-mgmt
  488     # gss-http
  591     # confFilemaker
  777     # multiling http

 

 

It is possible to add customizied ports to the default list. Just add a ACL in the "Config" > "Box" > "Virtual Servers" > "<Servername>" > "Assigned Services" > "<Servicename>" > "HTTP Proxy Settings" > "Advanced" at last line.

 

for HTTP ports

  acl Safe_ports port <portnumber>

 

for HTTPS ports
  acl SSL_ports port <portnumber>

 

 

In this example, the port 81 will be granted as http and https port with a comment after the hash.

  acl SSL_ports port 81  # https custmized
  acl Safe_ports port 81 # http customized
