Small issue with dynamic NAT pools. In my screenshot I have two different networks.
INT f0/1 on CORP router and below are on 192.168.1.0 /24 network
INT f0/0 on CORP router and to the right are the 209.165.200.0 /24 network
ESW1 has VLAN 1 as 192.16...
I have been working with GNS3 a lot over the last 6 months and have been learning so much. I setup a simple network the other day and suddenly PC2 doesn't ping to my default-gateway. It states "host (192.168.1.1) not reachable. PC1 pings fine. My set...
I have created a DHCP server with a router. I then created a switch that connections to the router. I have two hosts that connect to the switch. The first host obtained an IP address via DHCP. The second host will not obtain an IP address via DHCP se...
For some reason my hosts and servers cannot ping my router and vice versa. The hosts can ping each other in their VLAN. The servers can ping each other in their VLAN. The switches can ping the hosts. I have configured trunking between the two switche...
I created a topology in GNS3 with a router-on-a-stick setup.
I have a c3725 router on the right. To it's left interface connection is SW1. To the left of this SW1 is a second switch named SW2. To the top of SW1 is a PC1 and the bottom is a Server1. T...
Thank you everybody for your input. I use an ethernet switch and for some reason need to make sure the speeds and duplexes are exact. After correcting that I was able to ping again.
Every switchport connecting to my hosts have been configured to spanning-tree portfast. Here's what happens.....
After adding a host to the switch I enter the console of the host. I enter "ip dhcp." Then it says it cannot reach the DHCP server.
Then ...
I will probably stick with GNS3 then. I also have Packet Tracer but I found GNS3 to be more useful than Packet Tracer when doing certain functions. Thank you for the advice and I appreciate your time.
***Update***
Like I said when I turn off all of...
I am starting to think the same thing. I noticed a few Cisco functions do not work with this program. Momentarily I am going to play with the speeds and duplex type.
Other than GNS3 do you recommend any other network topology programs that may be bet...
