Cisco WAN :: 2921 Configuring As Gateway System

Apr 26, 2011

I'm configuring a 2921 Router.  It has 3 GigE ports, of which I'm using 2.  I would like the router to also act as a Gateway system between the 2 networks.  Can you tell me which configuration commands I need to accomplish this?

Understanding Subnetting And Classes?

Dec 8, 2012

I am currently trying to understand Subnetting via CCNA. My progress is going well,I understand the class below:

Class A 0-127 Max IP 2^24 = 16777216
Class B 128-191 Max IP 2^16 = 65536
Class C 192-223 Max IP 2^8 = 256

However I have seen an example from an ip calculator website, and noticed this :

Address: 11000000.10101000 .00000001.00000000
Netmask: = 16 11111111.11111111 .00000000.00000000
Wildcard: 00000000.00000000 .11111111.11111111
Network: 11000000.10101000 .00000000.00000000 (Class C) - I would have thought this would have been Class B?
Broadcast: 11000000.10101000 .11111111.11111111
HostMin: 11000000.10101000 .00000000.00000001
HostMax: 11000000.10101000 .11111111.11111110
Hosts/Net: 65534 (Private Internet)

Is this an invalid IP/masks as the max hosts is 65534 (which should be class B?). If so shouldnt the IP address range from 128-191- eg 172.16 (I know that CIDR is the amount of 1's. ).What calculates the class is it the netmask or the range of the first octet?

Windows XP Ignoring Default Gateway?

Jun 1, 2012

We have a Windows XP machine on our network that is giving us a strange problem. We have it statically configured with an IP and a default gateway address which points to a router on our network. This is the same router that nearly all of our machines point to and none of the other machines have this issue.If we open up CMD and make a ping request from an outside server (public or interal servers on other subnets) we get a 'destination host unreachable' error. We can ping the ip address of the router that is assigned as the default gateway. We can circumvent this ip address by adding a static route ('route add' from CMD) directing all traffic on the network interface to the ip of the router. Once this is done we can ping and get a response from any server both internal and external. We also tried doing a tracert (without have the static route added) to an external site by IP address. The tracert does not even show a hop for the router so it seems as if the request is never making it past the interface on the XP machine. We simply get an error saying it is unable to find the host. Interesting though it does provide us with a domain name for the ip address. So somehow it is able to reslove DNS. (We have a local DNS server on the same subnet)

Cisco :: LMS 4.0.1 / Understanding Change Audit Report?

Jun 27, 2011

I need to understand why change audit report reports an unused username Name of the user who performed the change. This is the name  entered when the user logged in. It can be the name under which the LMS  application is running, or the name using which the change was performed on the  device. #The User Name field may not always reflect the user name. The  User Name is reflected only when: A config change was performed using LMS. #A config change was performed outside of LMS, but the  network has username-based AAA security model, wherein authentication is  performed by an AAA server, which could be TACACS/RADIUS or local.

Cisco Firewall :: ASA 5505 / Understanding NAT For Both Version 8.2 And 8.3

Mar 1, 2013

ASA 5505 Version 8.2 or older nat (inside) 1 (INTF4) 1 (INTF5) 1 (INTF6) 1 (INTF7) 1 (outside) 1 netmask (outside) 1 interface
I believe this setup does the following. The inside interface and interfaces 4,5,6,and 7 will translate using this line....

global (outside) 1 netmask

and if the addresses run out is will start using the ouside interface IP address to translate, so traffic is not disrupted and is based on the line of configuration.....

global (outside) 1 interface
My question, does it do this because of the order of the configuration..
global (outside) 1 netmask (outside) 1 interface
or would it do it that way even if it was like this?
global (outside) 1 interfaceglobal (outside) 1 netmask
and if so why?Now let's convert the above configuration to ASA 5505 Version 8.3 or newer.
object network OUTSIDE-NAT-POOLrange network INTERNAL-SEGMENTSsubnet (any,outside) dynamic OUTSIDE-NAT-POOL interface
My question is how does it know to use the outside interface as a backup when the OUTSIDE-NAT-POOL is depleted?Also why do I need to define the INTERNAL-SEGMENTS ? Doesn't the "any" in the (any,outside) take care of that?Also wouldn't the "any" in (any,outside) cover interface 3 or DMZ which could be an issue?

8080 Understanding Safety Of Open Ports

Oct 28, 2012

I am a D-I-Y type of guy and have managed to setup Apache on my LAN and make it accessible via WAN over port 80 and Tomcat on port 8080.I aim to possibly get a home web server up (will calculate the costs), but I need some questions answered about networking.

My understanding on ports are that they can be a risk if left open (which I have done) if there is no service or application listening on my side on those ports.So I take it that leaving those ports open and removing the services or applications that run on my side for these ports is a major security risk?

I noticed though that Xampp (1.8.1) does not allow requests over WAN unless I set my password for Apache. Does setting this password imply that Xampp is safe to use in a production environment?

Cisco WAN :: 3825 Security Bundle Understanding

Dec 22, 2010

I need to understand security bundles. I purchased a Cisco Security Bundle, Advanced Security, 64F/256D. part number CISCO3825-SEC/K9. My expectation from this device was that I will get an IOS based firewall with no need for an additional firewall module. however, the supplier is telling me that I have to buy a firewall module to use the feature. Isn't the bundle supposed to come with all I needed since is a bundle?
Is there any command I can use to verify if this device is really what I paid for? what can can I check for in the sh inv and sh ver commands? I don't see any information from these commands.

VPN Gateway Via Cisco - Where To Place Windows Server

Apr 26, 2013

I am looking to add remote sites that will authenticate with the Windows Server using VPN via Cisco rv042 routers in a gateway to gateway setup.My main concern is the placement of the server to the router and what would be considered best practice.In my mind, option 1 seems to be what I want - however, this would mean disconnecting the WAN feed to the server (my ip is static and tied into the MAC address of the server). While option 2 doesn't look right to me, it would leave the existing configurations in place which would minimize my downtime (I think)

Security :: Configuring KalemSoft Media Streamer With Windows 7 (64bt) Firewall?

Jul 30, 2011

I have an hp envy 17, running windows 7 64-bit, and I'm having a problem getting a program, KalemSoft Media Streamer, to work on my laptop, so I can stream my laptop media to my HP TouchPad. I traced the problem down to windows firewall: When windows firewall is disabled, I'm fine, but I want it to work while it's enabled as well. I tried to add it to the list of exceptions but nothing seems to work. I've attached a photo of the error message, i can change the base data and control TCP ports for kalemsoft (currently 5030 and 5031.

Oct 10, 2011

Any document which expalins what you need to know when looking at purchasing an ASA5505.  Which clearly describes the verious permitations and combinations of these lovely little boxes?
I recently purchased a basic: ASA5505-BUN-K9

Cisco Switching/Routing :: Understanding Existing Setup With Two 3750s

Jan 10, 2013

We've recently inherited a platform with little handover and also minimal networking experience.We're going 100 miles an hour in learning, but I'm a bit confused with the idea of a L2 switch with no IP assignments to ports, so using VLANs, and a L3 switch with IP assignments. And the combination of both.We have 2 Cisco 3750 switches, along with a whole host of other hardware, so we're starting at this "gateway" to start breaking things down.

Cisco Switching/Routing :: Understanding Mls Qos Queue Set Output With 3750

Apr 16, 2012

I've been  working on breaking down and understanding the default auto qos  configuration on a Cisco 3750 in the hopes of putting together a QoS  strategy that will fit our environment.  I'm having some difficulty  understanding how the "mls qos queue-set output" syntax works.
From another post, at [URL], the author offers the following example and explanation;
mls qos queue-set output <1/2> threshold 2 400 400 100 400thresshold 1: 400%
thresshold 2: 400%
thresshold 3: 100% (implicit, not configurable)
reserved: 100%
max: 400%
However, I'm having trouble understanding what is meant.  Here, it looks like it's saying, for example;
mls qos queue-set output 1 threshold 2 400 400 100 400
How  come there is syntax stating "threshold 2" when in the succeeding part  the 400 refers to thresshold 1 and threshold 2 again?  The syntax 400 400 is, apparently, already referring to thresshold 1 and 2, no?
