While the first player behind the NAT joins fine, adding additional players is problematic in the default configuration. Symptoms include rejected challenges, dropped delta packets, and severe &#8220;connection interrupted&#8221; messages.<\/p>\n<p>By default, Quake III clients send and receive data over the same port, causing the server to treat multiple clients as a single data connection. Quake III does have the ability to specify individual client ports for communication by adding a command line switch.\u00a0 Follow the procedure below to add this switch.<\/p>\n<p>1. Right click on the QIII icon<\/p>\n<p>2. Choose &#8220;Properties&#8221;<\/p>\n<p>3. In the Target field you&#8217;ll see a line like &#8220;<b>C:\\Program Files\\Quake III Arena\\quake3.exe<\/b>&#8221;<\/p>\n<p>4. Add the Quake III net_port command to specify a unique communication port for each system. The complete field should look like this:\u00a0<b>&#8220;C:\\Program Files\\Quake III Arena\\quake3.exe&#8221; +set net_port 27660\u00a0<\/b><\/p>\n<p>5. Click OK.<\/p>\n<p>6.

This is also an option with the Linksys if you want to disable Multicast PassThrough.<\/p>\n<p>&#8211; TCP 1494 is a registered port for ICA. Some ISPs may filter this port for residential service. You can test this by using Telnet to contact the host (Citrix Server) using port 1494. You should receive a sounder that consists of two block characters and the letters ICA repeating.<\/p>\n<p>&#8211; If the Citrix Server is hosted on an NT Server, the following applies: The NT TCP port allocation algorithm is to index the ports used from the minimum user port (1025) upwards. A counter is maintained of the last one allocated, and is incremented for each allocation. A check is then made to make sure no other connection is using this port, and if so, the algorithm iterates until it finds a free port. The NT TCP\/IP ports are a function of how many other connections have been made, and are not random. The maximum user port used by default is 5000, but a registry key &#8220;Max UserPort&#8221; can set this up to the TCP\/IP maximum of 65534.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>You have a Linksys Etherfast Cable \/ DSL router and are having problems with: Setup \/ Basic Functionality Firmware upgrades (including MacOs issues) Security, VPN\/PPTP, PPPoE Port Forwarding \/ Special Applications \/ Dynamic DNS \/ Logging  9\/3\/01 Citrix client setup info 8\/11\/01 PCAnywhere connection problems 4\/26\/01 Using the SPI &amp; Triggered port features Update 8\/3\/00 Accessing mapped LAN-side servers (&#8220;loopback&#8221;) Update 11\/30\/00 Remotely obtaining your WAN IP address 11\/28\/00 mIRC Help\u00a0 2\/15\/01 Using the logging feature Update 10\/1\/01 Getting certain applications\u00a0and games\u00a0to work. 7\/14\/00 Using TZO Dynamic DNS service. 8\/3\/00 Updating Dyndns.org when your IP address changes. \u00a0 <\/p>\n","protected":false},"author":2,"featured_media":5595,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/posts\/444"}],"collection":[{"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/comments?post=444"}],"version-history":[{"count":1,"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/posts\/444\/revisions"}],"predecessor-version":[{"id":8492,"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/posts\/444\/revisions\/8492"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/media\/5595"}],"wp:attachment":[{"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/media?parent=444"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/categories?post=444"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.practicallynetworked.com\/wp-json\/wp\/v2\/tags?post=444"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
