Cisco Firewall :: NAT To IP Address Not Directly Connected To PIX 515
Mar 27, 2012Can an ip address be NAT'ed to an ip address on a PIX 515 which isn't an ip address of a network directly connected to an interface on the PIX?
Specifically, can a host with an ip address of 150.140.102.3/26 which is connected to a network whose PIX firewall interface is 150.140.102.1/26 be NAT'ed to an ip address of 150.90.70.1/24 which is not a ip address of an interface that is directly connected to that same PIX 515?
I've attached a PDF depicting the network topology and describing the above.My first response to this question is that it can't be configured to do this, but need either a confirmation or correction to this.

Mar 28, 2013I'm trying to configure a 2800 series router. .I'm consoled in and put a basic config on the router (see attached). After putting this basic config on, I plugged it into a small unmanaged switch, changed my laptop's IP and plugged it in the switch also. I can't ping the router from the laptop and vice versa. This is the second switch I've tried this with, so it must be.The first switch, I installed at location, connected a cisco cable to it and a local server, so i could remote in and finish configuration. In that scenario, I had plugged the switch into a managed switch and had the same result as I'm getting now--can't ping IP addresses (can't ping the switch's IP, not can it ping local IPs).

Apr 11, 2013I am trying to test (if possible) the idea of having 2 6509-E switches connected directly to each other while using VRF-lite (Sup 2T). The idea is to have 3-4 separate networks. For example Net-A, Net-B,Net-C, Net-D. There is no PE router*, just these two switches. Also, there sin't any other access layer switches. All users connect directly to the 6509-E's via switch 48 port switch blades.
Net-A and Net-B on separate VRF's, but able to talk to each other. Net-C and Net-D* on separate VRF's without being able to talk to any other. Net-D* will have a PE since it comes from an external network. This is something I would like to test in a lab environment, but I am not familiar with VRF's.

Cisco Switching/Routing :: VPC Pair Of Nexus 7K And Servers Connected Directly
Jan 9, 2012My Data Center has one single core switch where is connected several servers, one port is the link to the router wan and other port is the link to the FW, my boss wants to install 2 nexus in order to replace the single switch. All my network has only one address, for example 192.168.10.0/24 if I connect two nexus 7010 in VPC and Domain, each nexus is going to has 2 modules with 48 port 10/100/1000 rj45 and i wan to connect servers directly to each nexus, with this figure i'm going to have a group of servers connected in two different nexus, Do they can have the same network 192.168.10.0/24 considering that the nexus are in the same vdc and vlan and have only one gateway for both groups? If the answer is positive, which nexus would be the gate way for that address, the primary or secondary? Or i must have a different address for both group of servers, i mean for example 192.168.10.0/24 and 192.168.12.0/24?thus each nexus would be the gateway for that new address?
To have two nexus connected by VPC in a Domain mean that one computer connected to one nexus can share the same address or vlan with other computer connected to the other nexus????

D-Link DIR-655 :: Router Is Not Recognizing Laptop As Directly Connected Device
Oct 27, 2011I have a setup where there are two networks. A 172.16.0.0/16 and a 10.1.0.0/16 that are separated by the dlink router. I am able to ping from the 172 network to the 10 network using a laptop that is directly connected to the router and that laptop can also browse the web fine. However, I cannot ping to that router or access that subnet at all from the 10 network (if I try to access its LAN (the 172 network)). The 172 network is on its LAN and the 10 network is its WAN. I can access its WAN fine. Also, there the router is not recognizing the laptop as a "directly connected deivce" but its not preventing the laptop from using the router. I have tried to make the router as least secure as possible but still nothing.
I thought about making Static Route to point towards the router's LAN but the only option it gives me is the WAN for the exit interface.
D-Link DIR-655 :: Slowing Internet Down But Fine When Directly Connected To Modem
Jun 9, 2011I have been using my DIR-655 for about 2 weeks now with Road Runner wideband services. Starting yesterday my internet became very slow and I discovered the cause was the router. I tried resetting it to factory settings and things will be fine and run smoothly for about 5-15 minutes but after that it goes back to being extremely slow. My speed tests would go from 10ms (normal) to 250-450ms. Before this issue occurred the Dlink was perfect, had full speeds. I am running a wire Ethernet connection.
I am currently using revB and tried upgrading firmware to 2.01NA which had no effect, but make my internet seemingly go back to normal for the first few minutes then nosedive again. I have also changed my speed/duplex settings in Network Config to 1gbs Full Duplex. I've also disabled QoS, and still no change. Not sure what else to do. When directly connected to the modem everything seems fine. The modem is also the provided Motorola SBG6580 which I have called Time Warner to set the modem into bridge mode and have the DIR-655 connected to it.
Cisco Switching/Routing :: 3750 Receiving CDP Packets From Switches Not Directly Connected
Jun 27, 2010A specific switch port which happens to be part of a 2 switch 3750 Switch Stack is seeing multiple CDP packets from 3 extra switch port interfaces that are not directly connected. Noteworthy is that the far end devices have the correct CDP entries and I physically confirmed at least two of those connections that lead to the switch "upstream to the culprit switch". Tricky part is that its production so room for maneuvering is limited. At some point I disabled all Ports save for the real uplink and the problem momentarily disappeared. Re-enable the interfaces problem resurfaces. Is there an explanation, technique to eliminate the culprit with minimal disruption?
View 4 Replies View RelatedCisco Switching/Routing :: 7206VXR - WCCP Redirection Of Non-directly Connected Subnets
Jul 18, 2012I have a Cisco 7206VXR running 12.4(24)T3 IOS. It is configured with WCCPv2 using L2 mask redirection. I am using service groups and associated extended ACLs to select which subnets I want to redirect port 80 traffic from.
It is working fine for the subnet 192.168.1.0/24....
int gi0/2
ip wccp 10 redirect in
ip address 192.168.1.99 255.255.255.0
... however, there is OSPF running between the router and a Mikrotik device directly connected to this interface. The gateway addresses for all the client subnets are on the Mikrotik. Traffic from other subnets, e.g. 192.168.2.0/24, 192.168.3.0/24 come in on this interface and I want to redirect those too. But it appears that the redirection doesn't work for those subnets (I don't see any hits on the relevant ACL for any subnet except 192.168.1.0/24).
It seems like the router only wants to redirect traffic for subnets that it has an IP address in itself. Admittedly, all of the example configs i've found on cisco.com are for redirecting traffic from directly connected subnets but I can't find anything that denies thie possibility of redirecting any traffic that comes in on a given interface.
The question is, is this how WCCPv2 redirection works? i.e., the router must have an IP address in the subnet to be redirected?
Cisco Switching/Routing :: Ping Break Between ASA 5550 / 2911 (directly Connected Via Ethernet)
Aug 15, 2012we have the following setup for our network :
UserNetwork - ASA5550 - WAN Router 2911 - ISP Netowrk - Branch Routers 877s / 1941s
Since last week we started noticing this problem that the branch users started to complain of slow application response.. After verifying it with the ISP and middle network we noticed that if i ping from my machine (ie usernetwork) to the WAN Router interface (facing the ASA) , i get time outs.. which is strange cause this is directly connected to it via ethernet cable.

Understanding Subnetting And Classes?
Dec 8, 2012I 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: 192.168.1.0 11000000.10101000 .00000001.00000000
Netmask: 255.255.0.0 = 16 11111111.11111111 .00000000.00000000
Wildcard: 0.0.255.255 00000000.00000000 .11111111.11111111
=>
Network: 192.168.0.0/16 11000000.10101000 .00000000.00000000 (Class C) - I would have thought this would have been Class B?
Broadcast: 192.168.255.255 11000000.10101000 .11111111.11111111
HostMin: 192.168.0.1 11000000.10101000 .00000000.00000001
HostMax: 192.168.255.254 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?
Cisco VPN :: ASA 5510s / Remote VPN Users Need To Access Networks Connected By Static VPN
Oct 23, 2012I have five (5) sites all connected via static VPN tunnels. They are all using Cisco ASA 5510s running 8.4(4)1. Any internal IP on each site can ping any IP on a remote site, because of the static VPN tunnels. I have the external IP (routeable) addresses connecting to each other.
Site A: 10.1.0.0 /24
Site B: 10.2.0.0 /24
Site C: 10.3.0.0 /24
Site D: 10.5.0.0 /24
Site E: 10.10.0.0 /20
I have remote users who connect using Cisco AnyConnect 3.1 to Site E. They get a static IP within the 10.10.100.0 /24 subnet (vpnpool00) and can access anything in the 10.10.0.0 /20 subnet. So far, so good.No management wants users to access devices within the other sites, specifically Site A using teh same AnyConnect connection. In other words, they get an Ip address of say, 10.10.100.5 and now need to access a server on Site A's subnet or 10.1.0.5.I have checked my NAT statements and they appear to allow this, but so far when I do a ping I get the following: Routing failed to locate next hop for ICMP from outside: 10.10.100.5/1 to inside: 10.1.0.5/0 What am I missing? Is there a NAT statement that is wrong, or an access-list statement or possibly a static route?
Cisco :: Subnetting According To Number Of Hosts VLSM
Jun 1, 2011you can subnet to meet the number of networks required, or you can subnet to meet the number of hosts required. In which circumstances would you use either one? or are they both the same? am kinda confused.Is subnetting according to the number of hosts VLSM? and subnetting according to the number of networks required is not VLSM subnetting? Also I'm on CCNA 1 chapter 6, if the other CCNA 2, 3 and 4 has chapters explaining subnetting better cos It's totally confusing me atm.Also, is my understanding correct, when a company wants a LAN made, a network designer see's how many hosts they require in each of their LANS and then chooses an appropriate address class and subnets it? and to connect the LAN to the internet he implements NAT on the router that connects to the internet, and that router translates the internal addressing scheme that was created into a public registered IP address from an ISP? Also does he just make the address up? for example if he decides to use class C, he just picks any random number in the class C range and subnets it?

Subnetting - How To Calculate Network Address
Jan 11, 2012Given the IP address of 172.16.10.22 and the network mask of 255.255.255.240... answer the following:
What is the network address?
What is the broadcast address?
What is the valid host IP range?
What I have done so far:
Part 1 - Broadcast address
172.16.10.22 - 10101100.00010000.00001010.00010110
255.255.255.240 - 11111111.11111111.11111111.11110000
Researching different ways to find the Broadcast address I took the binary IP address and replaced all numbers with 1's for the host bits identified in the subnet mask and came up with:
172.16.10.31 - 10101100.00010000.00001010.00011111
Is that the correct Broadcast address?
Part 2 - Network address
I am not sure what is meant by the network address and all my research has come up with either MAC addresses (obviously wrong) or CIDR notation...How do I calculate the network address?
Part 3 - List of valid IP's
Using the same address 172.16.10.22/28 I did the following:
28 is closest to 32 (block wise) so 32 - 28 = 4... 2 ^ 4 = 16 (block size)
IP address listing:
172.16.0.0
172.16.16.0
172.16.32.0
172.16.48.0
172.16.64.0
and so on...
The IP address in question is 172.16.10.22 and falls in the 172.16.0.0 - 172.16.15.0 block...
Is this the correct list of valid IPs?
Cisco Firewall :: ASA 106001 Error Most Likely Due To Interface Subnetting
Sep 16, 2012 I have a slew of 106001 messages coming into ASA log, from the outside interface. it appears like most of them are for standard traffic, such as TCP 80/443. i suspect these messages are from clients on the inside who have initiated connections to the internet, but then the client abruptly terminates application of something similar. Server side finally issues a close connection, reset or something else. Here is an example, with the ASA address being 1.1.1.195 (changed to protect the innocent ).
Another theory is that the NAT ip for clients is different than the actual interface IP, so that is behaving differently. For example, once the xlate times out, the IP used for the xlate is no longer active and any return packets to the interface would also error out - be refused. If the xlate was using the interface IP, that it would always respond in some way?
I can bump 106001 down to notification (5) or informational (6) level.
Home Network :: Subnetting A Single Static Ip?
Jun 18, 2012I am in the process of acquiring a static ip address from my isp time Warner. I only want to pay for a single static, but I have a number of machines I want to put on the internet, a web server and a e-mail-server. Using a cisco router, a Cisco Rv 120w. Can I assign the static ip address my isp gave me to the Rv 120w and then crate a vlan to assign addresses to various computers. Or is this something my ISP does. I get the impression from the tech guy at Time Warner that this is something they do.
