Hey thanks for the reply, how do I make sure the code is the same?

Hi Guys, I currently have two cisco switches (3750) and would like to add a 3rd to the stack, will doing this require downtime of the other two or switches?

can you explain in more detail please... much appreciated!

We have two core 4506 switches, these feed a number of 3750’s Stack1 : 3 3750’s connected with custom Cisco cable Stack2 : 2 3750’s connected with custom Cisco cable Stack3 – a single 3750 on its own (at present) We have 8 internal VLANs : 172.33.1.0, .2.0, .3.0 etc What we want to do is add...

I have remote access to a switch and I need to find out the software image whether it is enhanced or standard. The model is a 3750 but I need to find out exactly which one: WS-C3750G-24T-S WS-C3750G-24T-E WS-C3750G-24TS-S WS-C3750G-24TS-E Thanks

Yes the last hop IP address (our Public carriers address) is appearing twice. I thought it may be a routing loop. Is there anything else I can do to troubleshoot as I dont have access to the router? Thanks!!

If you tracert to one of our external IPs – you get a double hit or duplicate on the last hop. Does anyone know why this might be happening? EIGRP is running on the routers!

Here is my scenario; I have a DSL connection coming in from my ISP… IP address 217.x.x.3. My internal network has an internal address of 192.168.1.0/24, my exchange server is on this subnet and smtp traffic is being routed through our current firewall/router. I have just been given a Cisco 2600...

Thanks so much for your reply. One more question... Since I only have one IP I will have to create NAT mapping for incoming traffic. Is the following command correct and would it apply?? static (inside,outside) tcp xxx.xxx.xx.1 smtp 10.10.0.2 smtp netmask 255.255.255.255 0 0 Thanks

Can you post a sample of what you mean? Thanks

Hey thanks for the reply! I should of been more clear in my statement. Our ISP does host all our email and pushes the traffic directly to our exchange server after it has been scanned for spam and viruses. But my main question is what acl will I use to allow smtp from those servers...

Hello, I have one external public IP and I have to allow mail in to my exchange server on port 25, I am using NAT/PAT. The only problem is that the ISP host's the mail on three servers. Can I create an access list to allow SMTP in for each of the servers IP address or if I just allow all smtp...

Hi Geoff, Did you manage to get a resolve for this... I am in the same situation as you and its driving me insane.

Thanks for the reply! I tried changing the ACL but it is still the same. When logged onto the console I can ping the outside interface but not the gateway. Could it be a NAT/PAT issue.. How do I allow all traffic just to test, this would do no harm as I am on a test network.

Hi, No our DNS server reside outside the PIX. All other comms seem to be okay. Paul

Hi Guys, Hopefully somebody can help as I am new to configuring cisco firewalls. I have setup a PIX that is connected directly to our ISP router, I seem to have the configuration right but none of the inside clients can access the internet. I may have an ACL problem but can't identify it. Has...

I setup systems for small/medium clients and I standardise on the PIX515E firewalls & MS SBS 2003 for uniformity. I used to have someone configure the firewalls for me but he is often too busy now and I hate to bug him. I can do some of the simple configuration parts but I need assistance on the...

Hi Folks, I have been given the task of replacing our current firewall with a cisco PIX 515e. I have a 100 user network 192.168.1.x /24 and I have one public IP address: 217.X.X.102 /252. Can somebody please give me some pointers or even a sample config of what I should do. I have beginner...

Hi Folks, I am trying to use CPDM to config my firewall.. After accepting the first two ssl certificates it then gives me a hostname mismatch error. I think I fixed this by adding the hostname to the IP in the host file.. However I still cant seem to get in.. It keeps loading with the egg...
