Not sure if I understand your last post, but one suggestion - before finishing the simulation always double check your config using "sh run" or "sh start" Peter Mesjar CCNP, A+ certified pmesjar@centrum.sk "The only true wisdom is in knowing you know nothing.

You already wrote them: QoS and STP. I'll just add - everything about STP, as well as VLANs, basic Security (AAA,802.1x,access-lists), SPAN ... Check out this: http://www.cisco.com/warp/public/10/wwtraining/certprog/testing/current_exams/642-811.html Peter Mesjar CCNP, A+ certified...

If you need better and centralized control of creating and deleting VLANs, configure VTP (Virtual Trunking Protocol). This way one switch will act as VTP Server, sending VLAN config info to VTP clients and only VTP Server can delete VLANs. However be aware of that even VTP client can erase VLAN...

One more thing - is NVRAM replaceable in 800 series routers? Maybe you would be fine by just replacing the NVRAM with new one than buying the whole router. Peter Mesjar CCNP, A+ certified pmesjar@centrum.sk "The only true wisdom is in knowing you know nothing.

> Is it a problem that 3 routers are port forwarding? Is there a technical reason why that wont work? I can't think of any issue if it is configured correctly. To configure port forward on Cisco router I think this should do it for your setup: ip nat inside source static tcp 10.0.0.4 80...

0x2102 tells the router to look for boot command in NVRAM and - if not specified otherwise by boot command - load IOS from Flash 0x2142 tells the router to boot without loading startup config from NVRAM and load IOS from Flash Peter Mesjar CCNP, A+ certified pmesjar@centrum.sk "The only true...

Search the net - there are tons of free ones. If you want to pay, there is Testking, Boson... but don't forget experience using real routers!!! Peter Mesjar CCNP, A+ certified pmesjar@centrum.sk "The only true wisdom is in knowing you know nothing.

Well I guess you had a book for older exam. Check out this one: http://www.ciscopress.com/title/158705146X# If you are considering a book, one word - CiscoPress:) Peter Mesjar CCNP, A+ certified pmesjar@centrum.sk "The only true wisdom is in knowing you know nothing.

Short answer to your question: NO Peter Mesjar CCNP, A+ certified pmesjar@centrum.sk "The only true wisdom is in knowing you know nothing.

You are mixing IP addresses too much. From the routing table I can see you use: 192.168.3.0/30 <-- why? why not rather eg. 192.168.4.8/30? 192.168.4.0/30 192.168.4.4/30 192.168.7.0/24 <-- why? why not rather eg. 192.168.2.0/24? and why not start from 192.168.0.0? 10.1.3.0/24 10.1.2.0/24...

sorry not: ip nat inside static tcp 10.1.1.101 3389 192.168.1.2 3389 but: ip nat inside source static tcp 10.1.1.101 3389 192.168.1.2 3389 Peter Mesjar CCNP, A+ certified pmesjar@centrum.sk "The only true wisdom is in knowing you know nothing.

Would that allow me to map another port to another node using the same 192.x.x.2 addy?" Yes it will, however your config is wrong. Port forwarding command syntax is: ip nat inside source static tcp|udp INSIDE-IP INSIDE-PORT OUTSIDE-IP OUTSIDE-PORT For you: ip nat inside static tcp 10.1.1.101...

It can take about a minute till switches put their trunked ports up and running, which is not because of trunk config but because of STP. However since you want trunking, you are going to separate users to VLANs, aren't you? So there will also be end host disruption as you will be assigning...

As long as you don't want to allow interVLAN communication and you have at 4 ports on firewall, two for each company, I can't think of any problem with this. But maybe a firewall can be an issue, in which case you will need a separate firewall for each company. However there is absolutely no...

If 192.168.1.3 is not really configured, your Cisco 3661 will not know how to handle packets with this destination address. In other words port forward to fictious IP addresses does not work. How about creating a forward to 192.168.1.2 instead of 192.168.1.3? What masks are you using with...

Just one host is mask of 32 bits, or 255.255.255.255. Inverse this and you will get a wildcard of 0.0.0.0 Peter Mesjar CCNP, A+ certified pmesjar@centrum.sk "The only true wisdom is in knowing you know nothing.

What kind of cable do you use to connect modem to Cisco switch? I know nothing about your cable modem to say for sure what cable you need to connect, but I would say you need straight-through TP cable. Ports on Cisco switches are made "cross-over" directly. Also check the config of the switch if...

You are saying that you have problem, but - you don't explain what is the problem... And also can you explain your network setup so we will have more insight on how your network operate? One more point - you are saying: "Here is my fully functional config (with the exception of the Port...

snickm, modifying admninistrative distance as I showed you is one way. narbik, why do you think his addressing is messed up? I think his addressing scheme is does not look nice but so far I can't seem to spot any problems due to messed up addressing. Where do you see the problem? Peter Mesjar...

What I think is that your router will try to load-balance returning packets. Looking at your routing table: S 10.1.2.0/24 is directly connected, Dialer1 is directly connected, Serial3/0.1 Path to 10.1.2.0/24, from where you source your traffic, is bound to Dialer1 and...
