ASA怎么再配置PPPoe的同时，能配置DDNS吗？让ASA把运营商分配的动态公网IP同步到域名，如果能怎么配置，谢谢各位

Hi there,
1/ DDNS update integrates DNS with DHCP

2/ PPPoE is not supported in conjunction with DHCP because with PPPoE the IP address is assigned by PPP.

3/ Configuration Examples for DDNS

4/ From the above, PPPoE not support DDNS, advised use static IP address or DHCP.
