DDNS of RG-EG3250
182 2 2024-7-5 11:07:05
Hi Everybody,
Sorry if my English no good. I have a problem about DDNS, Management IP, Egress IP of EG3250.

I have:

+ two Wan (Wan 1 : PPPoe, IP Wan 1:; Wan 2 : Static IP, IP Wan 2: Wan 1 connect to Gi0/9, Wan 2 connect to Gi0/6

+ DDNS: I choose Public IP, If I choose Wan IP, I can't choose Gi0/9 (it is grey out). Therefore I can choose Auto ( or Gi0/6 (

+ Management IP:

+ Egress IP:

If I want to change Management IP and Egress IP to, I go to IP-Based Route and choose Default Route of from "Primary Route" to "Back up route-1". And then I choose "Back up route-1" to "Primary Route" (I run Balance load). But when Router reboot, the Egress IP is changed to, I can't connect with my recorder camera (It use Domain name) and another application as VPN error

Because I have a DDNS with Domain name, and I want Egress IP is alway is to some application : VPN, IPTV, VoiIP. How can I do ? Please help me to solve this problem.

Thank you everyone !

Dear Mr Gtac-Micca,
When I writed this question, I has changed some IP, sorry about this.
Wan 1, Wan 2 go to DI4(Gi0/9), Gi0/6 of EG3250. And Gi0/1 (of E3250) go to Firewall. From Firewall goto switch core => switch acess is IP Server of ISP (Wan1-PPPoe) is gateway of ISP (Wan 2-Static Wan)
