本人在单位上网，连接echolink后能看到自己在线状态，但是怎么也连不上其他的友台。而在家里上网连接没什么问题，经防火墙、路由器测试结果（图片）
windows xp service pack 3
local ip address: 192.168.1.58
firewall test results: fail
测试成功通过tcp端口5200连接到echolink服务器。说明你的tcp端口设置设置可以正常使用echolink。
the tester was unable to communicate over udp. if you have internet security software installed, be sure it is configured to allow echolink to access the internet. if you have a router or firewall, be sure it is not blocking udp ports.
there appears to be a router between this computer and the internet. a router normally requires special configuration for use with echolink.
for more information, click the help button above, or see the firewall solutions page on the echolink web site.
请教哪位老师能给解答？谢谢
