HAProxy: No, not applicable for TTL-based attacks.
IDS Suricata: Yes, detects unusual TTL traffic patterns.
WAF: No, irrelevant for TTL manipulation.
OWASP Rules: No, unrelated to TTL-based threats.
Complex anycast solution – WEDOS Global (or Cloudflare for example): Yes, handles TTL manipulation efficiently.
Solutions
Configure routers to drop expired TTL packets early.
