how do I whitelist IP addresses on the R7500v2?
I'm having issues using a plugin for Claude called Claude Code. I'm getting ECONNRESET. In my router logs I see [DoS Attack: ACK Scan] from source: 44.215.74.30, port 443 [DoS Attack: ACK Scan] ...
It looks like my ISP (Centurylink) was blocking Claude Code. I used a VPN and now it works.
I talked to Anthropic (who owns those IPs) and they said
> When a user's applications make requests to Anthropic's API, they initiate an outbound connection to our servers. The IP addresses they see (44.215.74.30, 52.39.32.173, 35.186.224.46) are our response servers sending data back to them - this is standard client-server communication.
Which makes sense. So why would Netgear see that traffic as a DOS Attack in the logs?
I can't edit that. They also said:
>Anthropic never initiates inbound connections to customer networks. All communication flows outbound from their network to our endpoints, with responses coming back through the same established connection.
>Your router's DoS protection is incorrectly flagging these legitimate API responses as threats.
