TCP - Method used FTP server |
---|
1)In Your client machine(LAN)you have to run FTP server 2)In router configure Trigger port 443:443 and Target port 21:21 3)External network(WAN) try to access ftp server of client machine using router uplink ip address(Goto terminal enter ftp -p 192.168.2.30) ftp port 21 will not start util you trigger any packet flow on port 443 in your client machine 4)In your client machine(LAN)run https service(In browser https://www.google.com) 5)Goto to your external network(WAN),try access ftp server of client machine(ftp -p 192.168.2.30).incoming traffic on ports 21 after seeing an outgoing packet on port 443 |
UDP - The Netcat ( |
1)In router configure Trigger port 443:443 and Target port 2399:2399 |
TCP - iperf is a tool to measure the network performance. |
1)In router configure Trigger port 443:443 and Target port 5001:5001 |
By default Port triggering will be disabled in the RPI .We can enable using two methods .One is through DM and other way is through UI
DM :
dmcli eRT addtable Device.NAT.X_CISCO_COM_PortTriggers.Trigger.
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.Description string Myservice343
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.TriggerProtocol string TCP
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.TriggerPortStart uint 8080
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.TriggerPortEnd uint 8090
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.ForwardPortStart uint 3000
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.ForwardPortEnd uint 4000
WEBUI
Step 1: Login to webui, from navigation -> Advanced ->Port Triggering. Click on Add Port Trigger.
Testing Steps (TCP and UDP)
TCP :
Router configure Trigger port 443:443 and Target port 21:21.
From External network(WAN) try to access ftp server of client machine(LAN client) using router uplink ip address(Goto terminal enter ftp -p 192.168.2.30 in WAN client),
while client machine(LAN)run https service(In browser https://www.google.com)
UDP :
Router configure Trigger port 443:443 and Target port 2399:2399.
In Your client machine(LAN)you have to run : nc -u -l 2399
From external WAN machine run nc -u 192.168.2.30 2399, while client machine(LAN)run https service(In browser https://www.google.com)
DM :
dmcli eRT addtable Device.NAT.X_CISCO_COM_PortTriggers.Trigger.
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.Description string iperf
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.TriggerProtocol string TCP
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.TriggerPortStart uint 443
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.TriggerPortEnd uint 443
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.ForwardPortStart uint 5001
dmcli eRT setv Device.NAT.X_CISCO_COM_PortTriggers.Trigger.1.ForwardPortEnd uint 5001
WEB GUI:
Step 1: Login to webui, from navigation -> Advanced ->Port Triggering. Click on Add Port Trigger (Configure Trigger port as 443:443 and Target port as 5001:5001)
Step2: In Your client machine (LAN)you have to run: iperf -s -B 10.0.0.106 -i 1 -p 5001 (10.0.0.106 - LAN IP)
Step3: In the WAN machine run iperf -c 192.168.161.216 -p 5001 -i 1 -t 60 -B 192.168.160.173 (192.168.161.216 - router uplink ip address, 192.168.160.173 - WAN PC Ip) same time in the client machine (LAN)run https service (In browser https://www.google.com)
