Comparison of Routing and Switching Capabilities in Proxmox

  1. Routing Capabilities:

    • OpenWrt: Basic routing capabilities are ideal for small networks. It supports static routes and some dynamic protocols (like OSPF and BGP) through plugins, but is generally limited in comparison to OPNsense or pfSense. Lightweight, and good for a Proxmox VM where minimal overhead is desired.
    • OPNsense: Advanced routing capabilities, including support for dynamic routing protocols like OSPF, BGP, and RIP. It provides policy-based routing, multi-WAN, load balancing, and comprehensive VPN support. Works well in Proxmox for a wide range of network sizes, from small labs to medium-sized business environments.
    • pfSense: Similar to OPNsense, but with an even broader range of routing capabilities. It supports comprehensive dynamic routing protocols (OSPF, BGP, RIP), advanced multi-WAN configurations, load balancing, failover, and full VPN support. Ideal for complex routing tasks, especially in environments where redundancy and VPNs are essential.
    • VyOS: Offers the most advanced routing features among the options, with support for a full range of dynamic routing protocols (OSPF, BGP, RIP, IS-IS) and advanced capabilities like MPLS, VRFs, and QoS. It is suited for enterprise-grade networks and is a powerful choice for advanced routing tasks in a Proxmox environment.
    • IPFire: Basic routing capabilities focused on static routing and some dynamic protocols (OSPF with plugins). Limited compared to other platforms and more oriented towards firewalling than complex routing tasks.
  2. Switching Capabilities:

    • OpenWrt: Supports VLAN management and tagging, but lacks full Layer 2 switching capabilities. It's more of a Layer 3 router/firewall with some VLAN features.
    • OPNsense: Provides basic VLAN support and can bridge interfaces to simulate some Layer 2 functionalities but does not offer full Layer 2 switching capabilities. Best used for environments where routing is the primary focus and VLAN separation is needed.
    • pfSense: Supports VLANs and VLAN tagging (802.1Q) with some basic bridging functionality. Like OPNsense, it does not function as a full Layer 2 switch but can handle VLANs and work well in environments where both routing and basic switching are needed.
    • VyOS: Primarily focused on Layer 3 routing. Limited Layer 2 capabilities and is not intended for full Layer 2 switching tasks. VyOS is more suitable for advanced routing than for switching.
    • IPFire: Offers basic VLAN support but lacks comprehensive Layer 2 switching features. Primarily designed for firewall and routing tasks, not switching.

Ideal Use Cases in Proxmox for Routing/Switching:

  • OpenWrt: Best for lightweight routing tasks or home/lab environments where minimal system resources are available. Limited switching capabilities, so it should not be relied upon for environments that require extensive Layer 2 functionalities.
  • OPNsense: Good for environments where both advanced routing and some VLAN management are needed. Ideal for SMBs or advanced home users using Proxmox to virtualize multiple network appliances.
  • pfSense: Excellent choice for complex routing needs, including multi-WAN, VPN, and advanced network configurations. Can handle some switching tasks like VLAN tagging, but is not a full Layer 2 switch.
  • VyOS: Best for enterprise-level routing scenarios that require support for advanced dynamic routing protocols (e.g., BGP, OSPF, MPLS). Not suitable for Layer 2 switching but excels in complex Layer 3 tasks.
  • IPFire: Suitable for simple or smaller networks where basic routing and firewalling are needed. Limited Layer 2 and dynamic routing support make it less ideal for larger or more complex network environments.

Integration with Hardware Like Unifi, Cisco, Fortinet, and Check Point:

  • Unifi: OpenWrt, OPNsense, and pfSense can integrate well with Unifi hardware for small to medium networks. VyOS may be overkill for Unifi setups unless advanced routing is needed.
  • Cisco: VyOS, pfSense, and OPNsense are suitable for integration with Cisco hardware, supporting advanced networking protocols (BGP, OSPF). OpenWrt and IPFire are less suited for Cisco environments requiring advanced routing.
  • Fortinet: OPNsense and pfSense are most suitable, supporting secure configurations (VPN, IPsec, etc.). VyOS can also integrate well for advanced routing needs.
  • Check Point: pfSense and OPNsense provide good interoperability for secure deployments, while VyOS can support advanced networking. OpenWrt and IPFire are less ideal in these cases.

Conclusion:

  • For Advanced Routing: Use VyOS for enterprise-level needs or pfSense/ OPNsense for SMB environments.
  • For Simple Routing: Use OpenWrt for lightweight needs or IPFire for basic tasks.
  • For VLAN and Basic Switching: Choose pfSense or OPNsense as they provide the best balance between routing and some Layer 2 functionalities.
