Kirti, The 3COM system setting defaults to 1514. We use radius to set MTU and we leave the 3com system to it's default. We don't use FreeRadius, so I can't say where it is in the configs. -----Original Message----- From: usr-tc-bounces+adam=semo.net(a)mailman.xmission.com [mailto:usr-tc-bounces+adam=semo.net@mailman.xmission.com] On Behalf Of Kirti S.

FW: [USR-TC] RE: Dial-In Problem!!!!
by Kirti S. Bajwa 30 Jan '06

30 Jan '06

Hello: For the last few days I have posted the following question: ============ Please help. This problem is going on for the last 7 weeks without fixing. TC1000 1-HiPer NMC 2-HiPerARC 10-Hiper DSP We are a small ISP (400 customers). We have 2-ISDN-PRI lines for our customers to dial in. Our entire system looks like this: / / T1 to External Internet / CISCO 26XX Router | HUB 10/100 | ---------------------------------------------------------------| | | | | | NMC ARC1 ARC2 Web Authentication ----------- 3Com ------------ Server/Email | | | | | | | | | Customer Dial-In Our customers can dial-in, are authenticated and can access the internal web site (www.tibonline.net) and retrieve their email. But when they try to connect to any web site (outside our network) on the external net (such as www.yahoo.com) they time out with a message saying that "this page can't be displayed". We have changed the HUBs, RJ45 cables. We have the CISCO Router tested fine. Finally, I replaced the 3COM box with a backup box and the problem continues. Interestingly, we can access any Internet web site (www.msn.com, www.yahoo.com, etc.) from our internal network (over LAN) without problem. ============ Since posting the above message, we have received a number of responses. Charles suggested to see how the CISCO 2600 was assigning the IP addresses (or something similar!!). For the last two days, AT&T technicians has been working with me to look into the router. They have setup static address and have done number of settings without success. I have switched 3COM to a backup 3COM box. Following are new the IP address: NMC (Port 17) 12.21.237.240 ARC1(Port 15) 12.21.237.241 IP Pool: 12.21.237.48/31 ARC2(Port 16) 12.21.237.242 IP Pool: 12.21.237.96/31 The problem is that out Dial-In customers can dial-in, access the internal network (email, authentication, DNS, Web Servers) but can not access the external Network (www.msn.com) etc. I have setup a dial-up PC (Win XP Pro) to test. The first time I connected, the IP address assigned was 12.21.237.98. I could not access the external network. I tried to do a external trace from www.traceroute.org. Following are the results of the trace. -------- Call this TRACE-1 Testing the network route from EASYNEWS.COM to 12.21.237.98...

In TRACE-2 (outside network is connected & the dial-in connection works), the trace gets to my dial-in terminal (12.21.237.99). I have noticed couple of things in the above traces. In both traces, ARC1[Kirti S. Bajwa] (12.21.237.241) is first traced even though the IP address of my terminal (12.21.237.98 or 12.21.237.99) is on ARC2 (12.21.237.242)!! Can someone explain why trace is always first going to ARC1 IP? Can someone explain what is going on? Why sometime the dial-in wotks (access the external network) and other times it does not? AT&T is going to call back around 3:00PM (EST) to help. Is 3COM needs some settings changed? Thanks in advance. Kirti

Scott, Make sure if you are using DC power that you are properly grounded. We ran into a problem very similar to yours, but once the chassis ground was properly established all the problems went away. We've not had that problem with AC powered units. -----Original Message----- From: usr-tc-bounces+adam=semo.net(a)mailman.xmission.com [mailto:usr-tc-bounces+adam=semo.net@mailman.xmission.com] On Behalf Of Scott Gusler Sent: Monday, December 26, 2005 10:16 AM To: usr-tc(a)mailman.xmission.com Subject: [USR-TC] Lost-Carriers/Rate Negotiaion Hello, I'm having a problem with these tc1000s creating a lot of lost carriers. Since these modems were installed they have been giving about 14% lost carrier rate. Since we discovered the problem we've been changing firmwares and trying to get this down but nothing seems to be working. Currently the tc is loaded with software version 5.3.110. We put the old pm4's in place and the lost carriers drop to 1-2% maximum, but with that another problem arises, we've had users calling in and complaining their connection speeds have been a lot slower. I'm thinking the pm4 negotiates a more stable speed for the modems than the tc1000's do and thats what causes the lost carriers in the tc1000 but i don't know. Is there any way to modify this or does anyone have any other ideas on what might be causing this. Thanks, Scott

resell ports
by PD TC 21 Nov '05

21 Nov '05

Is anyone using a Total Control to resell ports to other ISPs? If so, would you be willing to share the software you use to let individual ISPs monitor their online users or disconnect a user?
