Configure DHCP To Use Two Different Range Of IP Addresses?

Sep 5, 2011

Cisco WAN :: 1760 V - Unable To Ping External Addresses

Mar 1, 2010

I have a 1760-v router set up at my home lab and I am unable to access IP addresses outside my local network.  I have my Cisco router's fast Ethernet port connected to a small net gear router which then connects to my cable modem.  The Cisco router is able to ping local address fine, but when I try to ping an outside address or domain name it times out.  However, when I am at the CLI and type something like Ping { URL}, it resolves Google's IP address but it will not ping it.  I have IP DEFAULT-GATEWAY and IP NAME-SERVER both pointing to my net gear router and pointing to my ISP's DNS server.

Cisco Firewall :: ASA 5505 - Create ACE For Range Of IP Addresses

Nov 7, 2011

trying to configure our ASA 5505 (hence my request for the ASDM). However, I can go CLI if push comes to shove.
What I'm trying to do is allow a range of IP addresses on the inside interface (those which the DHCP server is doling out IPs which are XXX.X.XXX.14-140) to access email only (which is hosted offsite). They still need to access the file servers which are on the inside but nothing should be going out to the internet other than email.
I believe I have to create a Network Object which contains the IP range I wish to restrict. I can see where I add the Network Object but I don't know what the syntax should be to specify the address range.
I'm also not sure what the sequence of the ACLs should be and whether or not I can keep the default Access Rules in place. There are the two implicit rules: 1) Permit any traffic out to less secure networks  2) Deny any traffic to anywhere (which is superceded by rule 1, yes?)
To create an Access Rule like the one I desire, do I need to move the two existing rules down the list so that the new one will supercede both implicit rules?

Cisco Routers :: RV042 Firewall Multiple External IP Addresses

Oct 6, 2011

if possible with the RV042.Primary External IP address uses port forwards for some ports, all okay.I would like to have other external ip addresses assigned to machines on my lan.Basic host multiple web servers, on different IP addresses, using port 80. [code]
From what i am reading, it looks like the RV042 can do this, but I am not real clear what my rules should look like.
I would think my high priority rule for each external IP address would be to deny all traffic first for each machine on the lan.Then create one entry with source 202.x.x.2 port 80 -> ?
How should I set my rules to do this, and what settings should I have on the Nic of the second machine?

Cisco Routers :: RV 120W Can't Access Internal Servers By External Addresses

Oct 13, 2010

I recently cut over from a WRT54G to a RV120W.  I am having an issue where I type [URL] (for a server running on my network) in my web browser while on the internal network and it always comes back with the router login page.  Basically it is supposed to go out of the router and then come back in on the public IP address and hit that server.  There was a function on the WRT54G called "Filter Internet NAT redirection" which when turned off would allow this to happen.  I am not seeing a feature like this on the RV120W

Cisco Firewall :: Possible For 5505 To Route / Map Renaming Private IP Addresses Through Its External Port

Jul 25, 2011

I have purchased a subnet of 8 private IP addresses from my ISP. 109.x.x.128/29.The ISP has placed a juniper router within our data centre which is routing purely from 109.x.x.206/30 to 109.x.x.128/29 with the ip of fa0/1 set to .129.
I have linked a cisco 5505 to fa0/1 of the juniper from fa0/0 and configured its IP to .130. I have configured NAT to translate our client pool 192.168.16.x /24 address' to the internet.
Is it possible for the 5505 to route / map my remaing private IP addresses through its external port? I have tried creating a seperate VLAN for a DMZ for our servers to sit within but am returned with a subnetting error as VLAN for my external port is all ready configured within the same subnet.

Linksys Wireless Router :: How To Determine E4200 V1 Or V2

Jan 14, 2012

The support and registration pages for the E4200 wireless router ask whether I have a V1 or V2 router. There is no place on the actual router that identifies it as V1 or V2, and the Cisco Connect application doesn't display this infomation either. What I do know is the following:
Model name:               Linksys E4200
Model number:            E4200
Serial number:             01C10C18104423
Firmware version:       1.0.03 build 14
Software version:        1.4.12005.2
How do I determine if this is a V1 or V2 router? The software updates are version specific.

Linksys Wired Router :: BEFSX41 Way To Determine Connection Speed On Internet Port

Jul 30, 2011

I have a BEFSX41 connected to a Motorola SB6120.  I changed my plan for a hgih speed, but did not see it.Had a tech out and we found when direct connected to my computer, I get 50 Mbps.  When connected through the router, about 9 Mbps.  I swapped cables, but still the same.
Is there any way to determine the connection speed on the Internet port?  It seems that it only running at 10, when both the router and modem support 100.

Cisco Routers :: RV042 When Updating / Adding Mac Addresses / Table Is Always Sorted By IP Addresses

Oct 8, 2012

In  setup for old RV042 (V1),  when updating / adding Mac addresses, the table  is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware  the list  is random, thereby increasing the chance of user entering DUPLICATE IP addr  with diff Mac addr.  That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be  able to catch duplicate ip errors even if the system does not flag the  errors.  All Cisco smart engineers can you all get the dhcp entries SORT by  ip addresses.

How To Determine IP Of Our Switch

Dec 18, 2012

I'm the sole IT worker at this company and I specialize in everything but big, corporate networking so here's a dumb question. How do I determine the IP address of one of our two switches? I need a list of MAC addresses of connected devices so I can relabel all the cables that were mislabeled (and this is a managed switch). For the other switch, which was put in by someone who knew what they were doing, you just type ss3900 into a browser and tada, 3com Superstack 3900 login so apparently someone did some fancy DNS stuff or whatever.

For this HP Procurve, the idiot before me who got fired for completely screwing up everything didn't leave any documentation or labeling and didn't use the same IP address as the Cisco switch that was pulled out. Obviously the switch is invisible to my PC from an IP standpoint

Cisco :: Determine How Much Traffic Is LAN Vs WAN

Aug 30, 2011

I have a site with a 1700 router connected to a 2960 switch. For some of the computers on site I want to determine how much traffic is local to the LAN and how much is going across the WAN.

One strategy I've come up with is to reset the interface counters on the switch ports to the machines in question and after some time compare the total bytes in and out of the interface with netflow data from the router. My only concern is that netflow is not completely accurate about the amount of data that has passed through an interface.

Is there a better or more accurate way to accomplish my goal?

How would I detect this in the future? (A tracert showed nothing between host and target.) Would Wireshark show me this info, with reduced TTLs?

D-Link DIR-655 :: Determine If A Device Is Connected To LAN?

I was trying to determine the IP, and MAC address of an AT&T Microcell connected to my network. I have no physical access to Microcell. I have been able to find the IP address, in the logs of the DIR-655, but nowhere else. Shouldn't it be listed under SETUP -> NETWORK SETTINGS -> NUMBER OF DYNAMIC DHCP CLIENTS?

Cisco :: Determine If IPv6 Is Enabled On Nexus?

Mar 28, 2012

I am new to Cisco Nexus and recently my company auditor flagged out that IPv6 is enabled on our Cisco Nexus 7000 device when we are not IPv6 ready.

The auditors have flagged this out due to the following default CoPP configuration:

ipv6 access-list copp-system-acl-bgp6
ipv6 access-list copp-system-acl-hsrp6
ipv6 access-list copp-system-acl-icmp6
ipv6 access-list copp-system-acl-icmp6-msgs
ipv6 access-list copp-system-acl-ntp6
ipv6 access-list copp-system-acl-ospf6
ipv6 access-list copp-system-acl-pim6
ipv6 access-list copp-system-acl-radius6

ipv6 access-list copp-system-acl-tacacs6
ipv6 access-list copp-system-acl-telnet6
ipv6 access-list copp-system-acl-tftp6

Does the default CoPP enable IPv6?
