Cisco Switching / Routing :: 1841 - How To Use Both 2 Interface For Two Different Vlan
Jan 3, 2013we've to configure our router 1841 to use both 2 interface Fe for two different vlan (also the second has to go on internet).
Actually we have int Fe0/0 configured with an ip address 192.168.1.1 for lan1 192.168.1.0/24 and we will use the second int Fe0/1 with another ip address like 192.168.2.1 for lan2 192.168.2.0/24.

Apr 1, 2013I am using a Cisco SG-300 28 port switch in layer 3 mode as my default gateway for all my devices. I have two vlans on the switch, vlan 1 and vlan 4. Both are pulling valid IP addresses in their scope from the DHCP server, and both have valid DNS settings. I set a static route to the Internet on the switch to our firewall (192.168.5.254). All devices connected to vlan 1 are able to access the Internet, however all devices connected to vlan 4 cannot get past the switch. A tracert from one of these devices shows it hits the switch as the gateway, but gets no further. [code]

I have set up VLAN 2 on 192.168.2.0/24 with the switch as the DHCP server. The switch is connected to an RV082 router which is at 192.168.1.65/27. Once I figure out what I doing I'll eventually shift that to 192.168.1.0/24 or something similar. So I have my switch acting as the DHCP server for VLAN 2 but I can't figure out how to get it to access the internet.
I found this example to set up the DHCP server:

this works to get vlan 2 to serve ips

The RV082 doesn't support trunks AFIK and I'm pretty much a newb at this stuff. TIA. I guess I should get a real router and I most likely will but I'd like to get this working if possible before taking the next plunge.

Jan 22, 2012I have a 1841 deployed as my NAT device towards internet. NAT is setup so that internal addresses can access WWW. I also have some NAT translations opening speciic ports from outside to inside in the form: ip nat inside source static tcp A.B.C.D 443 A.B.C.D 443 extendable.
Now have an outside address/port setup with a public DNS reference and using NAT from outside to get access to the corresponding inside address. It works when being outside the LAN.
Now to the problem: From the LAN side of the router - i cannot access the public name. I can ping it - but my browser dont find the webserver behind the name. Someone told me it should be setup as "local firewall domain" - and i should set this up as "source NAT".

Cisco Switching/Routing :: 1841 - No Console Access When Booting - All Green LED On
Feb 29, 2012today I received a Cisco 1841 Router with a problem i have never seen before. Maybe this my 1st really,really broken Cisco Router. When I power the Router on, the fan and all lights turn on (green) and that's it. Nothing changes, also after minutes of wating. On console i don't get any messages and I already tried every BAUD rate possible. Switched the router off/on again and again. And no, it's obviously not a console problem of my computer, because i tried with different routers.

Nov 2, 2011I want to know is it possible to check Internet speed directly in the cisco router thru any command or activating any service in the cisco router?.As it is seen most of the times internet speed offer by ISP is different as compared to clients.and Clients most oftenly not satisfied with internet speed The problem is that our ISP has given us 100MB leaased line.But when we deployed in production network the speed is same as DSL.We have reported this issue to ISP they then carried out Iperf test by connecting laptop directly with the ISP router.They have tested the speed and it shows about 94-96 Mbps and argu that it is up to the mark and there is problem at your side(i.e our internal network).Now our internal network has cisco 1841 router connected directly to ISP 3825 cisco router.Our router has minimum configuration as required to pass traffic out and in.Our internal 1841 router is connected to switch to which different clients are connected.We have performed some online tests using different speed checking websites and also perform real time tests by uploading and downloading files.The speed is much low as compared to 100Mbps and it is nearly or slightly higher then as DSL connection. how can we check internet speed in the specified scenario?Is there any command or service available in cisco router to check internet speed as we want to check ISP connection speed directly thru 1841 router?what about authenticity of online speed checking websites?Any specialize software/tool you recommend to check Internet speed in specified scenario?

Jul 24, 2012Since two weeks I have a problem with the VLANs who I started to configure. I hope together we find the way.I have 5 VLANS configured in a CISCO 3560G switch. In my windows server 2003 I configured DHCP scope for each VLAN.One of the requirement to connect vlans each other is to put the IP of each vlan as gateway in the clients.So, how can I do to access to internet?. The ip of my Firewall are in one of the VLAN´s.When the configuration of the LAN only had one DHCP scope the gateway was the ip of my firewall. But now i don´t know how to configure the DHCP server, or the firewall, or the switch, or all of them To get access to internet.

Cisco Switching/Routing :: Blocking MAC From VLAN Access 2950
Dec 11, 2011We have a group of computers on their own VLAN. A router allows internet access while keeping them sandboxed. We don't want them accidentally connect to our production network. We blocked their wireless MACs in unauthorized WAPs. I'd like to do the same thing for their ethernet MACs on our switches, (a mixture of 2950,2960 and 2960G currently testing on C2960-LANBASE-M, Version 12.2(25)SEE2). I've been unable to locate the correct method on google, by searching these boards or in the command reference.
What is the best practice for blocking a group of MACs from accessing a particular VLAN on a network consisting of several Layer 2 Switches?
Cisco Switching/Routing :: 2970 / Routing To Internet Through Different VLan?
Apr 2, 2012We have 2 internet connections- one for production and one as a backup. The backup connection will be used for allowing guest visitors on a wireless network that is on a seperate VLAN.
We have the following networks:
VLAN 1 production, 192.168.1.0
VLAN 10 backup internet connection, 192.168.100.0, Interface 100.2
VLAN 41 wireless guests, 192.168.41.0, interface 41.1
VLAN routing provided by Dell 6224 switch and other switching is Cisco 2970 (L2) switches.Backup Internet router is SMC (Comcast)
I would like to allow clients on VLAN 41 access the internet connection in VLAN 10 at 192.168.100.1. Clients on VLAN 41 can PING and trace to the default gateway 100.1. VLAN 41 clients are also able to get DHCP info from VLAN 1. NSlookup fails when using the ISP DNS servers. NSlookup is suscessful when using our internal DNS servers, but web pages are not returned. It eventually fails.We've tried to set the DFGW on the clients to both 41.1 and 100.1 with no success.
100.2 know where to find 41.1 interface for the 41.0 network. The router/gateway can PING the clients on VLAN 41, 192.168.41.0 network and visa-vera.
It seems like the clients are not able to get through 100.1 to the internet or the gateway/router doesn't know how to get packets back to the clients.A static entry was made on the router that mapped back to the next hop at 100.2. 1 Someone alluded to a NAT issue, where the returning packets have information for the 100.0 network only and the internet router doesn't know to send the packets through to the 41.1 interface to the clients.

Cisco Switching/Routing :: 3750x - Denying VLAN Access To Other VLANs
Mar 18, 2013I've got a 3750x stack set up as my core switch (only a small-ish environment) - I'm shortly going to be deploying an enterprise wireless network with Corporate and Guest SSID's. I'm going to be putting all traffic from the Guest SSID in VLAN 244, and don't want it to have access to any of the other VLANs (1 (Legacy Eqpt), 4, 8, 12, 16, 20, 24, 28, 32, 248 & 252).
IP ranges for all the main VLANs are:
1: 10.0.0.x/22
4: 10.0.4.x/22
8: 10.0.8.x/22
12: 10.0.12.x/22
16: 10.0.16.x/22 etc etc (you get the pattern)
I'll probably give Guest traffic (VLAN 248) the IP range 192.168.10.x/22 (not because I NEED that many addresses, but it's easier for everyone to remember/understand if I keep the subnet masks the same all round). However I also have a CCTV VLAN (252) which already has the range 192.168.0.x/24, which some people in other VLANs WILL need access to.
So my question is: What is the syntax for the ACL on my 3750x (IP base - 15.0.2) to prevent traffic from VLAN 244 gaining access to any of my other VLANs. I'm making a broad assumption here that a layer 3 switch is perfectly capable of supporting that function? I need ALL the syntax for setting up ACL's - I've never done it before
My gateway device by the way is 10.0.4.1, and I do have inter-VLAN routing set up on the core switch (obviously).

Cisco Switching/Routing :: 2900 - Multiple Vlan Access On Standalone Switch
Feb 3, 2013The field engineer has a stand alone 24 port 2900 series switch that he has different equipment connected to and are segmented using VLANs. So for example, he's got ports 1-4 assigned to VLAN 10, 5-12 assigned to VLAN 20, 13-19 assigned to VLAN 30 and 20-24 assigned to VLAN 40. He would like all the gear on VLAN 30 to have the ablity to talk to all of the other VLANS, but VLAN 40 should not be allowed to talk with any other VLAN. Trunking would do no good here since the switch isn't connected to anything and you can only assign one VLAN per port.
Is there a way to do this within the stand alone switch? The only possible way I could think of would be to ensure that each VLAN has an assigned IP number (subnet) and doing this through access lists.

On the 2960 I have my laptop connected to port 45 and I have it configured as follows switchport mode access switchport access vlan 10
I assign my computer a static IP address of 10.10.60.84/255.255.255.0/10.10.60.100 with 10.10.10.11 as DNS server. When I do this, I can ping anything on the 10.10.60.0 network, I can ping anythign on the LAN 10.10.10.0 network. I am able to connect MSN messenger, I am able to do NSLOOKUP and get outside IP addresses to resolve. I am unable to browse the Internet though. I am not sure where the problem is at though. It doesn't make sense to me, as it is setup the same way as VLAN 41 which is the wireless network, and when users connect to that, they get out to the Internet with no issues.
