Trying to understand why Default Inbound Firewall Rule is Allow Any.
Normally routers have Default Inbound Firewall Rule of Deny Any. With Admin/User setting up exceptions to Allow specific Traffic from IP / Port to IP / Port.
Searches of PepLink FAQ turn up information on Outbound Firewall Rules, with little of anything covering Inbound Firewall Rules.
Searches of PepLink Forum turns up users having problems setting Inbound Firewall Rule to Deny Any, with exceptions to Allow specific Traffic.
Testing via Online Port Scanners show Balance One's Ports to be Stealth, other than responding to ICMP Ping. *Despite Default Inbound Firewall Rule set to Allow.
Can someone please Elaborate on:
Why Default Inbound Firewall Rule is Allow Any?
Why changing Inbound Firewall Rule to Deny Any and adding Exceptions above Deny Rule fails to work?
Can someone please point to Documentation on properly configuring PepLink's Inbound Firewall Rules to protect against Intrusion / Hacking?
