我正在尝试使用特定接口远程登录公共服务器。
# telnet -b 10.144.238.192 google.com 80
Trying 142.251.42.14...
telnet: Unable to connect to remote host: Connection timed out
如果我在同一接口上使用 tcptraceroute 进行测试，结果看起来不错。
# tcptraceroute -i net1 google.com 80
Running:
traceroute -T -O info -i net1 -p 80 google.com
traceroute to google.com (142.251.42.14), 30 hops max, 60 byte packets
