Routing & Security Policies

Configuration Steps

  • Configure virtual routers and static routes
  • Create security policies with allow/deny rules
  • Set up NAT for outbound and inbound traffic
  • Apply security profiles to policies

Policy Example

# Security Policy
Policies > Security > New Rule
Name: Internet Access
Source: Trust, Destination: Untrust
Application: web-browsing, ssl
Action: Allow, Profile: Default

# NAT Configuration
Policies > NAT > Source NAT
Original: 10.0.1.0/24, Translated: Interface IP
