| 9100EM blocking?
Hi. Got a question and pretty stumped at this point.
I run a server for a racing league and have the ports opened. It works because people are constantly connecting. My wife and I run the league and we generally both log in to administrate. And this is where the problem begins.
When either of us connects first, it works just fine. But when the other tries to connect, we can't. More in detail.. When she connects, she logs in correctly and ALSO sees the Lan IP if she wanted to go that route. If I try to connect after her, I get timed out. If we disconnect her and I try to connect, I'm fine. But then when she tries to, she can't and the LAN is removed.
Verizon just replaced the route. We had the actiontec and didn't have any issues. We encountered these issues a long time ago with a d-link and ended up just replacing the router.
Does anyone, PLEASE, have any idea on what's going on? I tried going through the manual and can't pinpoint the solution.
Thanks in advance.

| Now that you mention it, I saw something similar with my 327w. I could SSH from work to my home machine. But if I did it a second time, the second connection hung. It seemed to allow only one at a time.
However, when I tried again a few days later, it worked fine.
I'm currently not using the 327w, so I can't retest easily.

Let's move this over to our Verizon FiOS Forum because the 9100EM is a VZ FIOS specific router. |

Some further information would be helpful.
•Do you have a static IP address for your server?
•If not, are you using DynDNS or a similar service to map "mydomain.dyndns.org" to your server?
•When you and your wife try to connect to the server, are you doing so by DNS name, external IP address, or internal (private) IP address?
•Are you connecting from inside your LAN or from outside your LAN?
•Have you created any port forwards in the router for your server?
•You said "and the LAN is removed". What do you mean by that? |

Yes.

(see above)
•When you and your wife try to connect to the server, are you doing so by DNS name, external IP address, or internal (private) IP address?
We use an external IP address like everyone else uses to connect.
•Are you connecting from inside your LAN or from outside your LAN?
Like above, we use an external IP. That's how everyone else connects. We do have the option to connect by lan IP (ex. 192.168.1.xxx) but only 1 of us can do it at a time. When the other tries to connect, it times out.
•Have you created any port forwards in the router for your server?
Yes, all ports are configured. If not, nobody would connect. Everyone else connects fine.
•You said "and the LAN is removed". What do you mean by that?
Answered above.
As an update, what we have to do right now, If I connect using an external or internal IP, I have can connect without any problems. When she tries to connect, she get's times out. Same holds true if the process is reversed. What we have to do is for me to disconnect, and then AT THE SAME TIME connect and it works. But ONLY if we do it at the same time.
The other router supplied by Verizon (actiontech) worked without issues. So what we're doing isn't anything out of the ordinary. It seems like the router is blocking IP entries from the same IP source or gateway. |

This looks to me as if it is a problem in your server, not a router problem.

It's not the server. Nothing was changed from using the previous router (actiontech). When the new router was installed, the issues started. If it was a server issue, nobody would connect or we couldn't. The server works fine. |

said by DavidC  : We do have the option to connect by lan IP (ex. 192.168.1.xxx) but only 1 of us can do it at a time. When the other tries to connect, it times out. I have to agree with nwrickert . If you and your wife can not connect at the same time using the internal IP address, that rules out the router, since your requests are not going through the router. I would focus on getting that working first, then see if the problem still exists when using the external IP address.
A couple of thoughts regarding not being able to connect at the same time to the web server via internal IP address:
•Could you have a duplicate IP address on your internal network? Possibly a static IP address that is also being assigned as a DHCP address?
•Does the web server have a limit on the number of concurrent connections?
said by DavidC : •You said "and the LAN is removed". What do you mean by that? Answered above. I'm sorry. I still don't understand that statement. "LAN is removed" makes no sense to me.
said by DavidC : It seems like the router is blocking IP entries from the same IP source or gateway. I was thinking that the first of the two sessions might not be getting cleaned up in the router's NAT table, but the NAT table wouldn't be involved when using a local IP address to access the server.
Most routers will recognize a request to their own external WAN address and route it internally without the reuqest ever going out on the WAN. |

Although I cannot verify it directly, I believe the Westell may work a little differently internally that the Actiontec.
Actiontec (Rev.A-D) is capable of supporting more than 1 bridge, therefore may have a different internal structure than the Westell which is limited to only 1 bridge). On that basis, I'd say it's possible the problem is the router.
Swapping back to an Actiontec may be the solution. What level Actiontec were you using that worked? Why was it replaced?
Want to swap a Rev.A or a C for your Westell? |

If I switch back to the Actiontech, then the problem doesn't exist. Everything works fine. If I didn't, I would agree that the server is the issue, but it isn't. I've already tried that. So if that test works, then I can only assume that the router has a setting or something that isn't right. Which is what I'm trying to figure out.
I had an issue with a dlink router doing the same thing at one time. When they released an updated firmware just a couple days after talking to them, it fixed the issue.
The actiontech was replaced because the guides for our tv's weren't working properly. So they swapped it out. But they left me the old router.
To answer about having duplicate ip's... both of us are set to static and are set at different numbers. For some reason, we have to be at static or we don't have internet. Verizon doesn't even know why and they were here 4 times trying to figure it out. |

•Does this happen on the Actiontec or Westell, or both?
•What web server are you running?
•Do you have UPNP enabled in the Westell? Was it enabled in the Actiontec?
•Do you have more than one DHCP server on your network?
•Have you changed the default DHCP assignment range to exclude the static addresses you're using? |

I've gotta guess you tried the Actiontec reset back to factory defaults, stopping at each step along the way to verify internet connectivity with DHCP LAN connections, etc.
At what point does it crap out?
Well, if it was me, that's what I'd do. Then again, that's what you had to do when you put the Westell on line.
So, you have three static addresses assigned--two PCs and the server. Are they true static addresses, or DHCP reservation?
You said you run a server for a race group. What is the server OS or application? What ports are open for WAN access? How many can connect from outside? Is it possible the server itself has problems with multiple admins at the same time? Do you get the same behavior if one of you logs in to admin from the LAN and the other one logs in to admin from outside?
Even if you try to log in to the WAN address, if you're on the LAN then that's how you connect. |
