And UDP 500 is for ISAKMP which is used to negotiate the IKE Phase 1 in IPSec Site-to-Site vpn & is default port number for isakmp, used when there is no NATing in the transit path of the vpn traffic. This is why we need UDP 4500. Hope I am not confusing you, if yes, please...

运行closeport,重启计算机即可。cmd下运行netstat -an,你会发现相应的端口都已经停止了。如果希望打开所有端口,运行closeport -o,重启计算机即可。你可以自己将脚本中你不希望的功能命令掉,然后再运行它。[注意事项]1.运行本程序前,最好手工停用DCOM。方法如下,利用Windows NT/2000/XP标准集成的“dcomcnfg.exe”...
Internet Key Exchange (IKE) - User Datagram Protocol (UDP) port 500 Encapsulating Security Payload (ESP) - IP protocol number 50 或者是 NAT-T 之例: IPsec NAT-T - UDP port 4500 在家庭路由器上,这通常通过启用"IPsec穿透"来实现。 IETF 文献 ...
For example, this conflict can occur in the Windows IPsec Services service. The IPsec Services service uses UDP Port 4500. On DNS servers that also provide IPsec services, port conflicts could prevent the IPsec service fro...
