Hi , definitely you need some hands on experience for CCNP. if you cannot afford a lot of money for your lab the you could use GNS3 for simulation/emulation. Very good for emulating Cisco Routers but still missing many functions for emulating Cisco Catalyst switches. Then you could at least buy...

Hi, Since VDSL is another flavor of DSL technology there must be a DSLAM somewhere around the neighborhood. VDSL modem should be connected on the copper pair running from each factory to the DSLAM. Maximum available bit rate is around 50Mbps and is achieved at a range of about 1.2Km, then the...

CiscoStu , Did you manage to get any readings from your modem. The values of the parameters can show what is happening. I found a thread in a forum that explains lots of things http://mybroadband.co.za/vb/showthread.php?t=84785&page=12 i'm reposting... "If slow service is...

Hi CiscoStu, thanks i saw that tool before. But our provider does not use Cisco DSL routers. I found a link to a page that explains DSL in detail. Check this out (also the other links on the left panel) ADSL Technology and DMT http://www.kitz.co.uk/adsl/adsl_technology.htm I'm still searching...

Hi, I heard that it is possible to locate/identify problems on a DSL line from a DMT graph. Anybody knows any tips how to read the graph? Is it possible to manipulate any parameters ,from modem or DSLAM side , to fix problems on the DSL line? Thanks ======== Stelios

I see my mistake .. On my first post I wrote that I wanted to filter the VPN PPTP access to my PIX. I should say that I want to allow only a specific address to go through (the router and terminate on the PIX) as VPN PPTP and block the rest of the addresses. If somebody else tries to connect...

Hi again LloydSev, I have the pix behind the router. The router is doing port forward or Virtual server (1723 192.168.0.2) and is connected to the internet. The PIX is not doing port forward. How can the remote client see and connect to the PIX via VPN? Is the there a better way to do it? I'm...

Hi, yes "sysopt connection permit-pptp" was in the config. And I guess it should not be there. I have check on that command and it seems to allows pptp traffic to bypass access-list command statement checking. I remove the comand and tried again. It still allows me to connect to the PIX...

Hi LloydSev, The client computer connects via VPN to the PIX. The PIX is the VPN server. ============================ Stelios Agapiou

Hi , I want to filter the vpn pptp access to my PIX. The remote client has a static ip. My network is like this .. LAN<->192.168.1.21(PIX501)192.168.0.2<->192.168.0.1(router)internet The router is doing port forward for pptp I have tried these commands but they don't seem to be working...

There are many tools and utilities for cisco equipment in this website ...... http://cosi-nms.sourceforge.net/ Is anybody using any of those? ============================ Stelios Agapiou

Thank you all, the tips you gave me are very valuable. The reason I mentioned the 3COM router is because this is what we use for our customers. At home, I use the D-Link DI-704P upgraded to the latest firmware. The only drawback is the SNMP which is v1 and I don't think this can be changed...

Hi, I was wondering if simple broadband routers, having NAT and hacker pattern detection(eg. 3COM 857), are secure enough? What attacks should I expect from hackers, by having only the functions mentioned above, on my DSL router? Should I install a dedicated firewall device (eg. PIX etc.)...

Hi, there is another software out there but haven't try it yet. It has a free edition and a Pro (~$40) PRTG (Paessler Router Traffic Grapher) http://www.paessler.com/index_eng.html Maybe somebody who has try it has more comments on that. Stelios

Hi, There is a problem when I try to configure a Cisco 761 router using the Cisco Fast Step software. The router has IOS c760-in.rxd.NET3 4.4(4) The PC has the following configuration , with a given ip address, netmask and gateway. C:\WINDOWS>ipconfig Windows 98 IP Configuration 0 Ethernet...

Hi, I had the same problem and somebody from CISCO suggested using the KIWI SYSLOG DAEMON. http://www.kiwi-enterprises.com/

Hi, I have two CISCO routers connected using a leased line and ISDN as a backup. When the leased line is lost and the ISDN takes over I want a warning message on the computer of a specific user. How do I do that? Thanks in advance Stelios
