网络工程 - NAT 上的 RTP 问题 - 吾爱随笔录

我已经在 nat 后面配置了 SIP，但是遇到了 RTP 问题——即我无法进行任何语音通信，但信号正常。

请在下面找到配置

interface GigabitEthernet0/0
 description $ETH-LAN$$ETH-SW-LAUNCH$$INTF-INFO-GE 0/0$
 ip address 192.168.1.224 255.255.255.0
 ip nat inside

interface GigabitEthernet0/1
 ip address X.X.X.X 255.255.255.248

ip nat inside source list 111 interface GigabitEthernet0/1 overload

ip route 0.0.0.0 0.0.0.0 X.X.X.X
ip route 192.168.101.0 255.255.255.0 192.168.1.215

access-list 111 permit ip host 192.168.1.216 any
access-list 111 permit ip host 192.168.1.217 any
access-list 111 permit ip host 192.168.1.218 any
access-list 111 permit ip host 192.168.1.219 any
access-list 111 permit ip host 192.168.1.220 any

192.168.1.218 是我的 Sip 服务器
192.168.1.220 是媒体网关
192.168.101.0 是语音网络
