Connection to the Internet

  • dedicated (synchronous or asynchronous) or switched line connection
  • only one IP address, which can be allocated dynamically by the ISP
  • automatic dialing at user's or mail server's request
  • automatic hang-up after a defined period of inactivity
  • week scheduler for an alternate hang-up timeout
  • support of ISP modem multiseries
  • manual dial/hang-up via a WWW interface

Firewall / proxy server

  • separates the LAN from the Internet to protect from attacks
  • Insecure interfaces (connected to the Internet) are detected automatically
  • cache increases speed of data retrieval and enables the use of data even if a connection isn't established
  • proxy cascading enables the use of a parent proxy with or without ICP protocol support
  • if the ICP protocol is used it is possible to define a few cooperative proxy servers at two levels: parents (at ISP) and siblings (at partnership company)
  • ICP protocol effectively detects temporarily dead proxy servers and gives users continuous access to requested objects
  • ability to access a listed source server directly (where access is enabled for permitted IP addresses)

Supported protocols and services:

  • HTTP proxy for access to WWW pages
  • HTTPS proxy for access to secured WWW pages
  • FTP proxy for access to data at FTP servers directly from a WWW browser
  • FTP gateway for access to FTP servers by FTP clients
  • Telnet gateway enables terminal access by the Telnet protocol
  • RealAudio proxy for playing audio/video distributed in RealAudio protocol
  • SOCKS version 4 and 5 for the access of programs using SOCKS protocols
  • POP3 mapped link enables easy communication between mail client and mail servers in Internet without using Proxy+ mail server
  • DNS forwarder translates domain names to IP addresses
  • Mapped links enable the use of protocols without proxy support (for instance IRC services)

Disc cache

  • data stored to the cache from WWW and FTP servers increases the speed of retrieval by other users
  • supports HTTP version 1.1
  • advanced configuration of cached data validity verification
  • explicit time-to-live of cached objects
  • disabling of cache storage configurable

Mail server

  • sends and receives mail for many Internet mail boxes at one time using the POP3 protocol
  • full SMTP mail server for one or more domains 
  • messages from an e-mail box can be distributed to user groups
  • sorting of incoming messages according to configurable rulesets
  • users can send messages even if a connection to the Internet isn't established
  • intranet mail
  • automatic dialing occurs at defined periods, or if the number of outgoing messages exceeds a defined limit
  • week dialing scheduler
  • enhanced support of the ETRN command makes the full SMTP server applicable even on a switched telephone line
  • restriction of clients' relaying to the SMTP server can be configured to prevent the use of the server for spamming
  • carbon copy of incoming and outgoing messages to file
  • mailer masquerade enables the administrator to set the domain name in mail headers
  • configurable resend if any transfer errors occur
  • shorter interval between mail exchanges if switched line is connected
  • configurable timeouts in communication with Internet mail servers
  • configurable maximum length of outgoing messages
  • SMTP supports unlimited number of recipients of one message
  • it is possible to define list of external email addresses

Access restrictions and security

  • a list of enabled LAN segments and/or enabled IP addresses of Proxy+ users
  • access restrictions for listed or unlisted URLs
  • access restrictions by time, content type (pictures, MP3, ....) or service (FTP, RealAudio, ...)
  • each computer can use its own restrictions

Further features

  • user list with grouping ability
  • is configured via a WWW interface, access to the interface can be restricted
  • display of status information (mail transfers, dialing,..)
  • log files about dialing, mail processing, errors, and security violations information
  • WWW server for intranet
  • customizable error messages
  • customizable AccessLog.TXT logfile format
  • each parent proxy (parent or sibling) can have username/password assigned
  • customizable Content-Type association table
