I have 2 IP segments: (A) 192.168.0.0/24 and (B) 192.168.9.0/24.
They are routed by a router. Both access the Internet thru an ASA 5510. ( See Attachment)
Workstation B can browse the Internet and access workstation A.
Workstation A can browse the Internet but cannot access workstation B
Even on the ASA (gateway of worksation A) I have a route statement:
route inside 192.168.9.0 255.255.255.0 192.168.0. 254 (Router F0/0)
I don't know why it doesn't carry out that routing statement.
