🖧 Virtual Network

Introduction

EntrepriseConnect provides a complete virtual network infrastructure accessible from your browser. No hardware required — everything runs in the cloud while feeling exactly like a real Cisco or Huawei deployment.

Supported device types

Adding your first device

1. Navigate to Virtual Router in the left menu
2. Click + Add Device
3. Fill in the form:
   • Name (e.g., "Main-Router")
   • Type (select from the dropdown)
   • Management IP (auto-assigned if empty, or specify)
   • Role (Primary, Secondary, Backup, Member)
4. Click Add Device

Configuring VLANs

VLANs (Virtual LANs) logically segment your network. Example: Finance on VLAN 10, Sales on VLAN 20, IT on VLAN 30.

1. Click ⚙ Manage on a switch device
2. Go to the VLANs tab
3. Click + Add VLAN
4. Enter:
   • VLAN ID (1-4094)
   • Name (e.g., "Finance")
   • Network (e.g., 10.10.10.0/24)
   • Gateway (e.g., 10.10.10.1)

Best practices for VLAN design

• VLAN 1 is default — never use it for production traffic
• Reserve VLAN 10-99 for users, 100-199 for servers, 200-299 for management
• Use native VLAN tagging on trunks
• Always specify inter-VLAN routing rules

Firewall Rules (ACLs)

ACLs control which traffic is allowed or denied between networks.

Creating an ACL rule

1. Open device manager (⚙ Manage)
2. Go to ACLs tab
3. Click + Add Rule
4. Use the visual Firewall Rule Builder:
   • Priority: lower = evaluated first
   • Action: PERMIT / DENY / LOG
   • Source: IP, subnet or ANY
   • Destination: IP, subnet or ANY
   • Protocol: TCP, UDP, ICMP, ANY
   • Port: specific port or range

Common ACL examples

# Block Guest VLAN from accessing Finance
access-list 100 deny ip 192.168.20.0 0.0.0.255 192.168.10.0 0.0.0.255

# Allow HTTP/HTTPS to web server
access-list 100 permit tcp any host 10.0.1.50 eq 80
access-list 100 permit tcp any host 10.0.1.50 eq 443

# Deny all other traffic (implicit but good practice)
access-list 100 deny ip any any log

DHCP Pools

Configure dynamic IP assignment per device and per VLAN.

1. Open a router or L3 switch
2. Go to DHCP tab
3. Click + Add DHCP Pool
4. Configure:
   • Pool name (e.g., "LAN-Employees")
   • Network CIDR (e.g., 10.10.10.0/24)
   • Range: start-end IPs (e.g., .100 to .200)
   • Gateway: typically .1 of the subnet
   • DNS: e.g., 8.8.8.8, 1.1.1.1
   • Lease time: 3600s default

Routing and Protocols

Configure static routes, OSPF, BGP, and VRRP directly from the Routing tab.

Supported protocols

• Static routes — manual next-hop configuration
• OSPF (Open Shortest Path First) — interior gateway protocol
• BGP (Border Gateway Protocol) — inter-AS routing
• VRRP (Virtual Router Redundancy) — high availability
• WireGuard — modern VPN tunneling

Topology View

Click 🌐 Topology View to see your entire network as a graph.

• Drag devices to reorganize layout
• Click any device to open its configuration
• Auto Layout to reorganize automatically by type
• Connections between devices are drawn automatically

Cisco IOS / Huawei VRP CLI

Every virtual device has a real CLI with Cisco IOS and Huawei VRP commands.

Example Cisco commands

show version
show running-config
show interfaces
show ip route
show vlan brief
show access-lists
show ip arp
ping 8.8.8.8
traceroute 8.8.8.8
configure terminal
write memory

Example Huawei commands

display version
display current-configuration
display interface
display ip routing-table
display vlan
display acl all
display arp
ping 8.8.8.8
tracert 8.8.8.8
system-view
save
