Title: Unable to get WAN IP Address
Post by: peterwkc on May 22, 2024, 01:18:09 AM
Dear all forumers,

I had setup the necessary vlan and static ip for internal interface but my external interface cannot seems to get WAN IP Address. I don't know what my ISP settings changed. Please help.

Please specify your intended setup:

IPv4:
WAN usually has DHCP, static configuration could also be possible but less common.
All local interfaces have IP addresses from different IP subnets, usually something like 10.0.0.1, 10.0.1.1, ...
At least Outbound NAT needs to be enabled and a firewall configuration according to your requirements.

What did you do?


IPv6:
The same, but LAN interfaces in case of DHCP usually have Track Interface to deal with delegated prefixes (and some more configuration specialities according to your ISP).


So what did you do?

I did Wan with DHCP, signin using PPPOE username and password. Created vlan interface.

Firewall was basic inbound block outbound allow. All IPV4 only.

Previously, I can setup with my ISP but after some infra upgrade. My ISP seems to block it.

You can use either DHCP or PPPoE but not both - so which is it? Your ISP can tell you which is needed, only one will work.

Sorry, I'm using PPPOE with username and password.

Then you need those details from your ISP. They are specific to you only.
