Mar 14, 2012A quick query regarding setting up a local user on a Cisco 2811. I have setup a few users as they need to have remote VPN access into our edge router, this works fine and I'm happy with it. The only thing is that when they come into the office they now have logins to get onto the router, they do not have the enable secret so they can't exactly do a lot (plus I've created them with privilege 0 which cuts a few extra CLI options) but I'd rather not allow them access at all if possible.If they weren't on DHCP then I could setup an access-list but this isn't really an option, I could also set me up statically and deny everyone else, but yet again I'd rather not.Is there anyway to restrict telnet/ssh access based on user alone? So when they put in their login it just boots them out. I could setup something like RADIUS (and therefore remove the local users completely) but I think it will be a bit over kill for the sake of a couple of users.

Dec 29, 2010We have cisco 7600 Router with 76-ES+XT-4TG3C Module connected. The Module is getting detected after upgrading the Router with SRD5 IOS.Below are the testing which we have done on the Router but we are facing the issue while configuring the Transport mode LAN and Transport Mode WAN:Brief about this is:- 2 Cisco 7606-s Router with Module 76-ES+XT-4TG3C each.- two ports on 7606-s Ten2/1 & Ten2/2 are configured as a Transport mode WAN while Ten2/3 & Ten2/4 are configured as Transport mode LAN.- We connect Fiber Cable from LAN Port to MUX and from MUX to 2nd LAN Port of the same Router. Same thing we tested by using the WAN Port-MUX-WAN Port connection.- Now on MUX end LAN port, connected Single and Multi mode fiber and on 7606 end 2/4 port which is configured as transport mode LAN, using Multimode SFP module -> XFP-10G-MM-SR, port did not came up then replaced 2/4 port with single mode SFP ->XFP-10GLR-OC192SR port came up. this is testing for LAN.- For WAN testing on MUX end used WAN port and on 7606 end checked with single mode and multimode fiber and with single XFP-10GLR-OC192SR / mulimode XFP-10G-MM-SR SFP, port did not come up.Wanted to know 1) If we have to go for Transport Mode LAN then which SFP/XSFP Module should go with along with the Single/Multimode Fiber.2) If we have to go for Transport Mode WAN then which SFP/XSFP Module should go with along with the Single/Multimode Fiber.Anything else is required while configuring the Transport Mode WAN as this is for Packet-Over_SONET/SDH? 3) MUX Side change is required while connecting both of this Modes on Cisco 7600 Router.4) Is hardware of the Router is giving any issue? Though we tested by connecting Back to Back LAN Port as well as Back to Back WAN Port. In both the situation the Ports are coming UP.

Cisco :: ACL - Allowing Only One Host To Connect To Internet?
Jul 15, 2012I've got an 1841 router acting as the firewall for a LAN. It also does NAT and acts as the dialer for a PPPoE DSL line to the internet.
All is working fine, except now I need to allow a Tivo device to connect to certain ports on the Tivo servers on the internet. I want only the Tivo to be able to do this. The problem is that NAT is happening before my outbound ACL is checked, so even though I've got rules to allow the Tivo's LAN address out on all ports, it never works. I've verified this using a syslog server, and can see my external DSL IP trying to connect to the Tivo servers and being denied.
I've done things like this at work by NATting the appropriate internal host to its own external static IP address, which allows me to write rules allowing only that external address to do stuff. But I don't have multiple external addresses to work with here.
I tried applying my outbound ACL to the LAN interface of the router in the "in" direction (and removing the same ACL from the Dialer interface in the "out" direction), but that broke other things like the router's own ability to ping out to the LAN or to see a TFTP server on the LAN. I could maybe fix all of that with rule changes and inspect statements on traffic going out toward the LAN (not sure of this, think so), but I'm wondering:
Is there a better way to let just the Tivo makes outgoing connections to certain ports?

Cisco :: Allowing CRC Error Connections To Forward?
Oct 25, 2012This is actually on my home television network.... Uverse which uses one of those dumb 2wire modem, router, wifi, 4 port 10/100 switch combo devices. it is NOT my internet source. It is just for IPTV services from ATT. Short of replacing the 2wire gateway with a new one from ATT I have a good learning experience question to ask.
I have two switches available at my home to work with on this issue. A EHWIC-8 port Gig Switch in my router and a 24 port 3750E gig switch.
When ever I plug, any port, any cable, both crossover and straight, on the 2wire uverse device into either Cisco switch there are masses of CRC errors generated by the cheapy 2wire thing.
CRC being a layer1 issue in nature I have tried everything short of replacing the 2wire and that is next. There is one caveat.
When the CRC errors are generated and logged on the 3750 it just seems to continue to forward those frames to whereever they need to go regardless albeit a ton of errors.
On the EHWIC 8 port in my 1921 router it seesm to stop forwarding after about 10 secs of encountering CRC errors. What gives? Is there something special command wise that tells a switch to forward frames regardless of CRC errors? Is the 3750 able to deal with them and just forward away and the EHWIC card not able too?

The NAT is simple - PAT all traffic unless exempted to the IP address of the outside interface.If I do the trace from my internet edge router it works fine - so I know it's not soemthing my uplinks are filtering - but if I do it through the firewall, I get perfect responses until the hop where it hits the firewall interface - then nothing.Is there something I am missing that I need to do to allow traceroute to just work with all the rest of the traffic?
