This doesn't make much sense without a route.  Can you try a traceroute to the
fedora box address from the 192.168.236.80 box to see how/why it gets there

Hope it helps (all addresses are 192.168. Trimmed to compact the schema):


----------      ----------     -----------
! 1.3    !------!1.100   !     !gw 236.21!
! gw 1.1 !   !  !  236.74!-----! 236.80  !
----------   !  ! gw 1.1 !  !  -----------
               !  ----------  !
               !              !
           [Router1]       [Router2]

Router 1 is a PFSense and its IP is 192.168.1.1
Router 2 is "something" (it is managed by other person, and i think is
somekind of win server) and IP is 192.168.236.21

            

This still doesn't explain why the 192.168.236.80 box can return packets to the 
fedora at 192.168.1.3 when you said it didn't have a route going through 
192.168.236.74.   Can you check what routes you do have on 192.168.236.80 and 
traceroute from there to 192.168.1.3?

  

Apologies by confusing you. I forgot that "the other" CentOS had 2 NICs, this is the machine where i began these tests. It's in a remote site and now when listing the routes remembered that.

It's conected to the 1. network with a second NIC and IP: 192.168.1.102. Replies must be return by that iface, really?
[root@control ~]# route

I Configured a printer in the 236. network to use 192.168.236.74 as gateway and now i can access it from 1. Thanks.
[jose@IDi ~]$ ping 192.168.236.74

Thanks again
