I can't ping between computers on the same segment, help!!

[israel.roche]

Hello good morning, the query I have is, I have a network with segment 80 (192.168.80.X) but between computers connected to that network, they cannot see each other, nor ping the gateway (192,168,80.1 ). Does anybody know what is it due to??

I have this access list configuration on my switch; will it be something like that? What should I add or remove?

Greetings, I hope you can help me.

Hi,

I don't known in which interface you have configured the access-list 101, but try removing this line and tell us if work it

access-list 101 deny ip 192.168.80.0 0.0.0.255 192.168.80.0 0.0.0.255

hummm ok, it could be that line, i have already allowed it, i will see at the end of the day if i can ping between computers, and i will write to you again.. 

tnks!!!!

regards!!
