Hope this helps. Something to remember is that the different security levels have default permits and denies attached to them depending upon the flow of traffic. example: Higher number ---> lower number (default permit) security level-100 ---> security level-0 Lower number ---> higher number...

The one I had was just a basic 4-port Linksys router. It had the option to disable the Internet/NAT function and use it as a normal subnet to subnet router. It worked fine. The functions were limited of course. One subnet to one subnet only. And of course no VLANs (but that wasn't mentioned...

Does the ISP control the router or do you control the router? I'm just curious, because the ISP said you have to "ask" for a port mapping. To answer the question of opening port 3306 inbound to the whole network, Yes it can be done without specifying it for each workstation. Something like...

I'd put those two in a text file, so they can be pasted in. Sometimes after clearing the translations, you get another one before you can type fast enough to remove the static. something like this ==== copy paste together ======== clear ip nat translations * no ip nat inside source static...

Many of the soho internet sharing routers still have the feature where you can disable the WAN NAT stuff and just do normal routing. The Linksys routers I used to use at home could do that. Sorry, though I don't remember the settings, but the website has the docs. I'm on a Cisco 831 now and...

Yeah, with IPv4, the whole Lat-Long Geographic tracking of addresses is still hit and miss. The database is pretty much dependant upon what ISP is using what subnets and then going by the city the ISP is in and assuming the user is there as well. Once IPv6 is fully out, it'll be much easier to...

This one will give you a city location for an IP. http://www.geobytes.com/IpLocator.htm?GetLocation It told me what city I'm in, but I don't know if it's international or not. BierHunter CNE, MCSE, CCNP

Let's see if I understand the config here. If not, please correct me. Network-1 ========= Device-A 192.168.1.4 Network-2 ========= Device-B 192.168.1.5 with a NAT address of 10.0.0.5 If that's the case, then for Device-A to communicate with Device-B it has to talk to 10.0.0.5 instead of...

There's a redistributable .net framework ("dotnetfx.exe" or something like that). You can distribute that with your application. If you're using an installer like Installshield or something, you can have the .Net Framework configured as part of the install process. BierHunter CNE, MCSE, CCNP

Since this is in the Cisco Router forum, I'm assuming you are using a Cisco router in your connection somewhere? How are you configured? NAT, static translation for your server, firewall settings, DMZ, etc? BierHunter CNE, MCSE, CCNP

Thanks for the info. Don't really see anything there that could be causing it, but always good to double check things. Also, I'm sure you caught my mistake above in saying interface E1, when you obviously have been saying E0 all the time. ooops :) There's got to be a reason for this. We'll...

Just to help clear up any confusion, losing a link on an Ethernet port will not cause 'Administratively Down.' That would cause Line Down/Protocol Down. Admin Down is either caused by the Shutdown command, or by Port Security (on a switch, but not the case here). I have also seen a rare...

Depending upon the equipment and IOS version, you can specify the range of ports you wish to permit or deny. Such as denying ports 135 through 139: ip access-list extended MY_ACL deny tcp any any range 135 139 BierHunter CNE, MCSE, CCNP

Wow...lots of confusing info on the web about ARP. Here's my final conclusion. ARP is a part of the IP suite which is why it is often referred to as a layer-3 protocol. However, it actually operates at the Logical Link Control layer which is part of layer-2. If someone is studying for a...

I wish we could edit our posts. Here's another one http://www.lex-con.com/protocols/ip.htm Although ARP is considered part of the Internet Protocol suite, it operates at layer-2. Also just found this one. http://www.erg.abdn.ac.uk/users/gorry/course/inet-pages/arp.html I also discovered...
