I don't know if this is the right place to post this or not but here is it goes. I just set up my cisco lab at home to practice for my CCNA. Right now I have my computer set up with a 192.168.2.3 /24 address, the Catalyst 2950 its connected to has Vlan 1 with a 192.168.2.2 /24 address, and the E0/0 port on my 2610 Router has a 192.168.2.1 /24 address. the wasy i have it set up currently I am able to ping from my computer to the router. I am even able to telnet to the router. However When I connect through the console to the router I cannot ping the computer from the router. I have been racking my brain trying to figure out why its not working. And ideas?
what are your PC' default gateway and mask;
what is configuration on router ?
clear arp cache on PC and router; maube somethings are stuck there; run debug ip icmp on router and do pings again.
My PC set up is as follows
Default gateway: 192.168.2.1
I did run the debug ip icmp and it was receiving pings just fine. I just can't run a ping from the router back to the computer. Do I have to configure anything besides the IP address & subnet mask on the switch?
Firewall on PC ! Forgot about this, check and disable (windows firewall and/or another one installed)
Firewalls may block pings that are not originated by you on PC; but will allow ones from You to others;
Switch - layer 2 - does not get involved at layer 3 unless you ping switch or want to access it via Telnet. Switch will read MACs and build MAC table to foward packets to appropriate port(s).
