View 5 RepliesI configure for our office site to site VPN project. Now I configured already Site to site vpn between ASA 5510 and 1841 router.
HQ LAN
Branch LAN 10.2.1.0/24 >>> ASA 5510>>>>> 1841 >>> INTERNET <<<<<< 1841 <<<<<< 10.30.3.0/24 ^^^^ Call Manager 2851
Now can access from Branch LAN to HQ LAN each other. I face the problems that are
1) In branch LAN , they can access HQ LAN & resource , but cannot access internet. I didn't configure NAT on PH Router
2) Can I access internet from BRANCH LAN through HQ LAN to INTERNET. Or Can I access Internet from Branch LAN from PH Router directly while access to VPN to HQ LAN ?
3) In Branch Site , hard phone cannot work but soft phone on PC can call to HQ. Hard phone IP are same in Remote Network (172.16.1.0/24 ) . Is it problem ? how can I configure separately ?
Having an issue with a Cisco Linksys E1500 on a home network. The device has a feature to provide a guest wireless network but the guest network can't get to the internet. A wired connection is fine, as is the normal wireless network but not the guest. The cheesy thing is, that it doesn't list an option for what type of wireless security protocol you want on the guest network. I'm assuming that it uses the same security protocol that the normal wireless network uses, but who knowsEspecially weird is that it asks you what password you want on the guest network but then the guest network show to be insecure when you try to connectthought maybe it was something funky with some of my configurations so I went ahead and factory defaulted it and just set it up with an insecure network for both the normal and guest networks. This didn't solve it. The guest network still couldn't get to the internet. In fact, the guest network can't even ping the router.

I am using a CISCO 2941 DC-A router,For the PPP testing.I was using GL card from the GL communications.In the case of GL card it supports this below Feature"In MLPPP Simulation, NCP can be configured to send Packets over PPP links in the bundle or on the MLPPP bundle."My query Is in the Cisco Router 2941-DC-A,Is their support for sending NCP over PPP in the case of Multilink(MLPPP).Because I found out that in the case of MLPPP the Cisco router sends NCP packets over MLPPP only. How to configure the cisco router to send NCP packets over PPP in case of MLPPP.?

I have a 1801 router connected to a 3550 switch with a regular 802.1q trunk, and I am curious as to what may be causing the unknown protocol drops on the connected router interface.
The switch is without any configuration at all except the following for the trunk configuration on the interface connecting to the router.
Switch:
-interface FastEthernet0/1
-switchport trunk encapsulation dot1q
-switchport mode trunk
Router:
-Interface FastEthernet8
-switchport mode trunk
There is nothing connected to the switch other than the router so the dropped traffic must be originating from the switch itself.The unknown protocol drop counter on the router increments by one every 30 seconds, and I tried using a packet sniffer but nothing noticeble showed up.
I read elsewhere on these forums that it might be udld, but that is not enabled by default, and just to be sure I tried disabling it on the interface and as expected it said it was not enabled, so I am ruling that one out.I also read that it could be because the router is recieving traffic from other protocols than IP, but I do not see how it applies in this case.
what does a 3550 send every 30 seconds that my 1801 does not understand?Could it have something to do with STP?
The router 861 Fast ethernet have support for wan protocol L2TP ?

View 6 Replies View RelatedI'm working on setting up a couple of new WAN sites with 256K frame relay circuits back to our main building. Each new site has a new PVC, and both are pointing back to a PVC on a T1 at the main building. The main site has a 2801 with a single CSU/DSU WIC, and each new site has a 1841 with a 3560 connected to fa0/1. At both sites, I'm able to get the circuit up, and the serial interfaces at both new sites show up/up, and the subinterfaces at the main site also show up/up for both sites. Routing is being done by EIGRP, and both sites are able to establish the 2801 as an EIGRP neighbor, and I'm able to ping/tracert anywhere on our network by name or IP, so routing and DNS appear to be working. I can also ping both new routers from the main site. However, that's about all I can do. I'm not able to access any resources on our network (email/shares/internet/intranet/etc) from the two new sites. I can ping the new routers/switches from the main site, but can't ssh to them. I can ssh to them locally. There are no firewalls in the equation, and I don't think there are any ACL's in the picture either.
Can ping and tracert just fine anywhere on our network (from both the 1841, a PC plugged into the 3560, or a PC plugged directly into the fa0/1 port on the 1841), including out to the internet, by name or ip.Can ssh to local router, but not to anything that isn't localDNS is workingDHCP not working using ip helper pointing to DHCP scope on server at main site, have to use static IPCan't rdp to anythingCan't get emailCan't browse windows sharesCan't get to any websites, external or intranet. IE says "Website found, waiting for reply..." but eventually times out.
I did some testing for communication over certain port numbers using telnet and nmap, and found the following:
Can telnet to url.. and local intranet webserver on port 80 (http)Can telnet to two of our Exchange Servers on port 25 (SMTP)If I run an nmap scan on url...com, or our intranet webserver, it confirms that 80 and 443 are open, but the pages will not load. I am able to telnet (port 23) to a state mainframe via the internet that some of our employees use, and I do get the expected login screen. I tried erasing the config one of the new routers, and just added back the bare minimum config to get the circuits up (serial/ethernet interface configs, eigrp), but saw the same symptoms.
One other thing to note: the 2801 at the main site has three other frame relay sites connected to it on the same WIC as the new sites, all of which are working fine.
I just don't understand why I can ping everywhere I need to be able to ping, and port scans show that communication is open over needed ports, but the applications don't work.
We have one core switch and we are planning to add a 6509. Both are none VSS.All the access switches are Catalyst 3560 series.
We plan to have all 3560s to have a link to each of the core. Without VSS, it is not possible to etherchannel to both core switches correct?What protocol should I configure to prevent in case one core fails? HSRP, VRRP, GLBP?
Do I need to run spanning tree protocol? if so which one?What is the best way to connect from each Catalyst 3560 for load balancing and redundancy? One to each core?
I have got a cisco 1841 router. I am able to create different vlan in the cisco router and I have got only 2 ports, fa0/0 and fa0/1. Now, I need to create different network in the same router at least four networks. FA0/0 is used for external networks. Now I want to create 4 vlan in this router. Namely, 10. 10. 10.1, 10.10.11.1, 10.10.12.1 and 10.10.13.1. The FA0/1 is connected to a 48 port normal switch. In the switch I am going to connect the cable of all the 10. 10. networks. Is this possible to access creating four vlan and routing all of them to the external networks with the fa0/1 port only. Is dot1q possible with only the router and a normal switch or is there any other possibility for this case.

I am setting up a lab network to emulate our production network and am using a single 2851 to emulate both my MPLS provider (only running BGP, not actually running MPLS) and our ISP that we use for our DMVPN secondary network.
Because I am using one router to function as both service providers I am running VRF's to keep the routing tables separated. So far basic connectivity works fine, I can ping from the PE 'MPLS' VRF to the data center CE interface and the ISP side is working as well.

I am using 1841 LAN router. Recently some broadcast is happening in our network when some users are connected. I need to block them automatically by detecting who are they.
I can block them manually but i want router to detect them and block.
I know that the ASR 1002 has 4 integrated ports but the problem that I am having is that I need two of those ports to emulate a L2 switched port. Is that doable?
If not than I need to purchase the following module below. Is that price really true?
I am trying to figure out how to use a Cisco 1841 IOS router to take traffic from one interface and source NAT it out towards the Internet on one interface and at the same time NOT perform NAT when sending the traffic towards a different routed interface.
Here the RemoteSite has connectivity back to the MainCampus, but there is no need to NAT traffic from the one site to the other. They share the same umbrella of address space. However, the RemoteSite needs to have its Internet-bound traffic NAT'ed out to the Public Internet via a third interface. I know that I could just NAT everything out from the Remote Site and map the traffic back onto the same address space for intra-campus communication, but I'd rather avoid that and just NAT where I need to NAT it to the Internet.
I do have a caveat here: in the event that either the MainCampus or the Public Internet interfaces go down, I would like to failover traffic from the downed link to other good link. For example, I want to NAT all traffic (including "intra-campus" traffic) out via the Public Internet if the direct link to the MainCampus is down. For the other example, if the Public Internet direct link is down, I would just send out all traffic without NAT towards the MainCampus.
I am trying to roll out a new internet router. The problem I am faced with is the LEC only supports VLAN 1227 and greater, specifically they are assigning me VLAN 2528. I am able to create the sub-interface and setup dot1q encapsulation for VLAN 2528, but the vlan database does not have the ability to add VLAN 2528 to it so I am unable to get layer 2 up and going, thus preventing me from getting the implementation done.
View 11 Replies View RelatedI use an 1841 router as an internet facing firewall with a 10MB MetroE connection. Lately users started reporting slow internet download speeds and web pages timing out. Bandwidth reports do not show the link as being saturated so I looked at the interfaces on the 1841. The interface connected to the provider shows OK as far as errors but the LAN side of the router shows steadily increasing input errors. It doesn't show any other errors, no CRC, frame, runts, giants or overruns, just generic input errors. What type of errors are those? Nothing is being logged on the console.
I moved the connection to another switch ports and the errors continue. I switched it down to 10MB and also changed the switch and the errors slow down but don't stop. Interestingly, the switch side never shows any errors. What can I do here? I guess it can be a bad interface but that is such a rare thing that I am hesitant to replace the router.
