Hello... I have the following in a home lab: PC1----SW1----R1----R2----SW2----PC2, I have configured IPs and static routes, I can ping from PC1 to all equipments/interfaces but not to PC2 and in the same way I can ping from PC2 to all equipments/interfaces but not to PC1....... is this something of configuration in the hosts?
check default gateway on both PCs it has to be the correct one. (R1:lan for Pc1, R2:lan for PC2)
then check if they have a software firewall running in windows xp or later it can be enabled by default
Hope to help
