Hello, I have a application with a CPU 313C + CP343-1 lean connected with a router on internet. And a TP177B connected with a router on internet. The CPU313C is connected to the TP177B by MPI. Now I can approch the CPU313C over internet by the CP343-1 Lean. I had to set port 102 open for the IP adres of the CP343-1 lean. When I want to approch it over internet I have to fill in my WAN adres. This works fantastic! Here is the question: Now I want the same with my TP177B, but I can't get it to work. What I want is totransfer a changed project.I tried to connect by port 20, 21, 23, 25, 80, 102 and 123 but non of them work. There was only one port open and that was port 23 (telnet). I tested this with Shields UP (www.grc.com). Does somebody have an sollution. Thanks in advance Sep v.d. Borne Ensa Machinebouw B.V. The Netherlands |

Hi, i mean it isnot possibleto set one port open for more thanone IP addess. You should look to this FAQ -> http://support.automation.siemens.com/WW/view/en/26662448 Look to the document "VPN Connections with standard DSL Routers (Gateway / Gateway and Gateway / Client)" I mean this are for your exercise better and much saver -> VPN! Portforwarding are not so save! |

Oke I'm going to look what I can do with VPN. I found a site www.portforward.com and they also told me that only 1 IP adres could be connected to 1 port. |
