Looking for Network-Level DDoS Protected IPs (L3/L4) in Asia

Hi everyone,

As some of you may know, Gatewaysentry is shutting down IP Singapore its services by the end of this month (Sept 27). I've been using their Singapore IPs for network-level DDoS protection, and now I'm urgently looking for a reliable alternative in Asia.

My Use Case:
I'm running a Reverse Proxy (L4 TCP/UDP) to hide my backend server's real IP. Therefore, I don't need web hosting or L7 (HTTP/HTTPS) Cloudflare-style protection. I specifically need L3/L4 Network Protection with direct IP forwarding.

Requirements:

Location: Asia (Singapore is highly preferred, but Hong Kong, Japan, or South Korea are also fine).
Protection Type: Robust L3/L4 DDoS protection (Volumetric, SYN Flood, UDP Flood, etc.). Must be able to handle large attacks (several Gbps to TBs) at the edge.
IP Allocation: I need 1 to 5 clean dedicated IPs (expandable up to 10 in the future).
Forwarding: I need to be able to forward all TCP/UDP ports to my backend server (via GRE, WireGuard, IPIP, or a VPS where I can run my own Nginx Stream/XDP).
Budget: Let me know your pricing. Looking for something reasonable for an individual/small project.
If you are a provider that fits this description, or if anyone knows a good provider/service in Asia that offers direct IP DDoS protection (not just domain proxying), please drop a comment below or send me a PM.

Thanks in advance!
