====== List of Supported Services/Applications ====== Below are listed the applications that are supported by the Internet Gate (the list can differ somewhat depending on firmware version). The mentioned web page items refer to the [[web_gui:security_profile|security profile]] page for the **High**, **Low** and **AltCfg** profiles respectively. ^ Servers on the LAN network ^^ |Web server |If you have a web server on your LAN you want to be accessible from the Internet, mark this checkbox and enter the local IP number of your web server. | |Telnet server |If you have a Telnet server on your LAN you want to be accessible from the Internet, mark this checkbox and enter the local IP number of your telnet server. [[wp>Telnet]] | |SSH server (Secure Shell) |If you have an SSH server on your LAN you want to be accessible from the Internet, mark this checkbox and enter the local IP number of your SSH server. [[wp>Secure_Shell|SSH]] | |FTP server |If you have an FTP server on your LAN you want to be accessible from the Internet, mark this checkbox and enter the local IP number of your FTP server. If you whish the FTP server to be accessible on a different port than 21, enter that port number too. But keep your server still listening at port 21 – it is the FTP proxy in Internet Gate that will make the necessary port redirections. [[wp>FTP]] | ^ Services ^^ |PING receiver |Normally the firewall stops all incoming ping requests. If you want the Internet Gate (WAN interface) itself to respond to pings, enter 127.0.0.1 as IP address. If you want your PC to answer the ping request, enter the PC's IP address (but ping's should still be directed to the WAN IP address). [[wp>Ping]]\\ :!: Answering to ping is a considerable security risk, and is strongly disrecommended! | |SIP |Enable the built-in [[sip:start|SIP]] functionality (subjected to licenses) | |Remote configuration (Web) |Allow users on the Internet to access the web interface of your Internet Gate. An IP address and mask is needed (defining //from// which hosts the Internet Gate could be remotely configured, use mask 255.255.255.255 if only one such client). One can select to use http (with port 66), https (with port 78), or both. When accessing the Internet Gate from a remote site enter the global IP address followed by a colon and the port number (e.g. http://50.11.69.17:66).\\ :!: Security risk! Use only temporarily for support staff etc.! | |Remote configuration (Telnet) |Allow users on the Internet to access the command line interface (through //telnet//) of your Internet Gate. An IP address and mask is needed (defining //from// which hosts the Internet Gate could be remotely configured, use mask 255.255.255.255 if only one such client). The port number 57 should be used for such telnet connections. [[wp>Telnet]]\\ :!: Considerable security risk! Not recommended! | |Remote configuration (SNMP) |Allow users on the Internet to access use the SNMP protocol for monitoring and parameter settings of the Internet Gate. [[wp>SNMP]]\\ :!: Do not enable unless instructed by your service provider. | ^ Network Games and applications ^^ |DirectX |Allow playing games using the Microsoft DirectX communication module. Some games where many users can play with each other over the Internet demand that the firewall allows non-conventional data traffic. The "Lo" security profile is pre-configured for most such games (as "All" is checked at "Applications from inside" and "loose UDP" is enabled). Some DirectX-based games though might demand that the DirectX checkbox is enabled. [[wp>DirectX]] | |ICQ 2003a/Lite |Allow communication with other ICQ users. | ^ VPN protocols (pass-through) [[wp>VPN]] ^^ |IPSec |Allow a VPN tunnel using IPSec protocol through to a IPSec client on your LAN. See [[web_gui:ipsec_pass-through|here]] for further explanation. | |IPSec-NAT-T |Allow a VPN tunnel using IPSec over NAT-T protocol through to a IPSec client on your LAN. See [[web_gui:ipsec_nat-t_pass-through|here]] for further explanation. | |PPTP |Allow a VPN tunnel using PPTP protocol through to a PPTP client on your LAN. See [[web_gui:pptp_pass-through|here]] for further explanation. | ^ Other applications/protocols initiated from inside ^^ |Web |Allow web access ("surfing"). | |NNTP |Allow access to newsgroups. [[wp>NNTP]] | |POP3/POP3S |Allow reception of e-mail. [[wp>POP3]] | |IMAP/IMAPS |Allow reception of e-mail. [[wp>IMAP]] | |SMTP/SMTPS |Allow sending e-mail. [[wp>SMTP]] | |FTP |Allow file transfers on selected port(s). Check also the FTP proxy mode settings under [[web_gui:security_profile#General settings|General settings]]. [[wp>FTP]] | |RTSP proxy |Allow listening to some of the Internet radio/TV services, on selected port(s), by using the builtin RTSP proxy. [[wp>RTSP]] | |SSH |Allow logging in to servers using Secure Shell. [[wp>Secure_Shell|SSH]] | |Telnet |Allow logging in to servers using the Telnet protocol. [[wp>Telnet]] | |SNMP |Allow supervision and control of networks using SNMP. [[wp>SNMP]] | |NTP |Allow time synchronization. [[wp>Network_Time_Protocol|NTP]] | |Ping |Allow outgoing ping (a LAN PC pinging to a PC on WAN / Internet). [[wp>Ping]] | |IGMP/Multicast |Allow reception of multicasted data streams. Check also the IGMP/Multicast Proxy settings under [[web_gui:security_profile#General settings|General settings]]. [[wp>IGMP]] [[wp>Multicast]] | |RTMP (Macromedia Flash) |Allow audio/video streams by a Flash player (RTMP=Real Time Messaging Protocol). Some web TV services use this protocol. [[wp>Real_Time_Messaging_Protocol|RTMP]] | |Yahoo! Messenger 5.5 |Allow communication with other Yahoo! Messenger users. | |AOL Instant Messenger (AIM) 5.1 |Allow communications with other AOL Instant Messenger users. | |Net2Phone 1.0 |Allow utilizing the Net2Phone application. | |ICQ (Send Message only) |Allow sending messages to other ICQ users. To utilize the more advanced feautures check instead the "ICQ 2003a/Lite" box, see above. | |Administration (Telnet) |Allow (inside) access to command line interface by Telnet. [[wp>Telnet]] | |Administration (SNMP) |Allow (inside) access to internal SNMP Server. [[wp>SNMP]] |
