View 1 Replies View RelatedI have been having problems with my router. I have a Net gear N300 v2, but I am not asking for support with said router. Forwarding network traffic from the Internet to a server and then have it properly re-routed. I have never done this sorta thing before, but I want to go into a career in I.T. when I'm older. As a side note, I have already figured out that ditching the router requires to have a software DHCP server, which I am using Windows Server 2008 Data center and it's built in role as DHCP server.
DNS is also configured. The modem a Motorola Surf Board is connected directly to a Cisco Catalyst 2950, and that connects all of the rest of the network, also via a 3Com SUper Stack Hub, and a little 8-port HP Advance Stack J2610A, which connects to all of my wireless AP.
I have network consists of more then 20 cisco 2950/2960/3700 switches. I have configured port security in my switches. initially when i configured on my switches it worked fine....even for copule of months it worked fine. but suddenly it start creating issues and now i am not able to implement port security on switches. the configuration is same but there is no effect now. Same switches were fine but now even having same configuration it is not working. please see the configuration: [code]

View 1 Replies View RelatedI have a 3560 8 port switch. Int gi0/9 is trunked to another switch downstream. When I try to configure int gi0/10 to trunk to a switch upstream the interface on the switch goes down and I have to either reboot the switch or plug directly into the switch and telnet into it to turn off trunking on the interface. When I configure trunking on the interface on the upstream switch that connects to this interface the same happens on that switch. The upstream switch is a 3750 with 12 sfp ports. Several interfaces are trunking to other switches from this switch. Spanning tree is not configured on the 3750 at all , and is not configured on either gi0/10 or gi0/9 on the 3560. I was consoled into the 3560 during a reboot after the interface went down, a message came up that said something like "Spanning Tree returning gigabit ethernet 10 to constant state" Why would I get this message if spanning tree is not enabled on the gig ports on either end of the trunk? There is no loop to require spanning tree to shut down an interface. I have several other 3560's configured as I would like to configure this switch and they are trunking without issue.
View 8 Replies View RelatedI have an problem with my new Cisco 876 Router. I configured port forwarding to access internal network devices from the internet . This works good from external but with my old Fritz box I was able to connect to this internal devices from the same internal network with the dyndns address.
So here is a short review for this:
DYNDNS Address port tcp 80 - > 192.168.0.80 tcp port 80
from ex tern it works but with source address example 192.168.0.20 to destination DYNDNS address tcp 80 (maps to 192.168.0.80 tcp 80 ) it doesn't work. Is there any trick in the config of cisco to let this scenario work?
I need to configure the port forwarding on Cisco 887 to forward port 22 on Public IP to a LAN IP port 2200. I don't know anything on Cisco router at all, beside telnet to the cisco and quit . Any step by step command.

I feel like this has probably been asked a thousand times over, but it doesn't seem to work for me. TCP works fine. I can't find any definitive answers, I'm still a novice with the IOS.
The purpose behind opening the ranges of UDP ports to the interface and forwarding is because the people in question want to run a VOIP phone from their home, but they have a home grade Internet connection, so therefore no static IP. Also, they're not going to pay for a router to create a S2S VPN.
Also, from one of the remote sites for which there is a VPN ( the 192.168.6.X/24 site), the audio is only one way. The phone guy says "i need to open ports both way through the VPN), but I feel like that's already been done??
For my other site ( 192.168.15.0/24 ) I have an IPSEC over GRE tunnel going, I don't know about the status of the voice phone there..or if its even made it there
Here's my config...i'm redacting things like public IP's, VPN keys, and the like

We've been configuring our swtichports as follows for our 7945 and 6941 type VoIP Phones, but are having problems witht the 6901.
VLANS
Vlan 900 is a VoIP VLAN
Vlan 999 is a NULL VLAN and is shut down:
interface g0/1
switchport access vlan 999 {VLAN to direct data traffic to the bit bucket becuase a PC shouldn't be connected to this port}
switchport mode access
switchport voice vlan 900
mls qos trust cos
spanning-tree portfast
The 6901 phone doesn't support multiple VLANs, so our configuration above does not work unless vlan 999 is turned on (not good security wise). We got the phones to work also by removing vlan 999 and switchport mode access.
switchport voice vlan 900
mls qos trust cos
spanning-tree portfast
solution that provides the discarding of data for the access VLAN, while supporting the VoIP vlan for this phone?
I have two servers, connected on two(Different) 6513 directly connected switches. Both these servers are in the same Vlan.
I have to monitor communication these two servers. I have a system connected on one of the 6513 switch, where network tool wireshark is installed.
How to configure span port.

How can I implement this with Zone-based Firewall on my 1921?
I'm looking for something as simple as the port triggering function on a Linksys or Netgear router.
I have a non-cisco router with a public WAN address. This is conencted to a 3750 switch internally. The switch is the default gateway for all VLANs, and the gateway router has static routes back to the 3750. The Router provides NAT, no NAT is done on the switch.My requirement is to port forward port 29 000 so that I can access a server on VLAN4 via this port.
So, I have: Router: Port 29000 map to 192.168.4.1 (Switch VLAN4 address)
The question is, how do I route port 29000 from the 3750 to the server on 192.168.4.42 ? what exactly I should add in order to port forward port 29000 incoming form my router, to my server on 192.168.4.42.
I have the above firewall which is working as it should but I have came across an issue with a recent upgrade to Microsoft Exchange 2007 and Outlook 2010 Autodiscovery due to the way the port forwarding has been configured for Outlook Web Access (OWA) on the router.
The router is forwarding OWA requests to the exchange server on port 8080 and the default website in IIS on the Exchange Server under which OWA sits and unfortunately Autodiscovery has been set with an SSL port of 8080. I think the reason for this is that we have an RDP server and the router is forwarding all port 443 requests to this server. Due to this Outlook clients cannot connect to Exchange through autodiscovery and cannot therefore get FREE/BUSY and a few other things.
I have 5 public IP addresses and only use two at the moment, one on the ADSL router and one on this firewall. I have no spare interfaces on either the router or the ADSL router.
My question is, is it possible to have a secondary ip address set on the public facing interface and set different rules for this IP which would allow me to forward requests on that IP to a different server?

I would like to configure a 3750 switch port to be able to use two vlans. I know you can do this with a voice and data vlan, but what about two data vlans ? Say I have two devices, one on a 10 subnet and the other on a 172 subnet, but i only have one wall jack for both devices to plug into. So I use a mini switch to connect both devices and connect the switch to the wall jack; and of course this all leads back to one switch port. When I go to enter the switchport access vlan 172 cmd, how would I also make it so the device on the 10 subnet could route out ?

I understand basic access list and such though I am extremely rusty.

I am trying to port forward for Vuze and I am having a problem understanding the concepts at [URL] for working within two routers. I have a Zoom 5241 cable modem connected through a Motorola VT2442-VD for Vonage VOIP, then connected through my Netgear RangeMax WPN824v3 wireless router, to my computer. I am also running AVG internet security. Here is a look at my ipconfig /all:
C:Users

Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid
IP Routing Enabled. . . . . . . . : No
[code]....
However, I do not understand where to setup the static ips and where to drop DHCP to be able to port forward successfully. I have tried in Vuze to set up acceptable ports 51600 for TCP and UDP, but they continue to get this error: "NAT Error - Connect attempt to 67.60.124.173:51600 (your computer) timed out after 20 seconds. This means your port is probably closed." I do know that the Ip present is from my Vonage with my external IP address. I even tried to establish rules for TCP and UDP within AVG Firewall settings for the Vuze program.
I've been having trouble signing into the PSN and Sony have given me some TCP and UDP ports to enter, I presume they're the ports for PSN.
TCP Ports: 80, 443, 5223, and 10070 - 10080
UDP Ports: 3478, 3479, 3658, and 10070,
When you want to open new ports on the BT HomeHub you have to fill out this form, and I don't know whereabouts I enter these ports I've been given.
Is there a way to get more messages out of a 2950 set to syslog? I've turned every logging option I can find to DEBUG, but all I get in my syslog are LinkUp/Down messages and "Configured from console by console".
