RE: NETWORK ROUTES
I have two routers because I use one for internal users and other to use
with public internet servers. Ok? And I cannot manage or add new rules in
these routers because they are administrated by other company.
Can you help me,please?

This system is your gateway to the internet. You must have the
default route point to 213.250.143.242. All the networks on your
private network are known and can be specified in the route tables,
but you cannot specify all the internet routes. So, the above route
table should look something like:
213.250.143.240 0.0.0.0
172.16.4.0 172.16.16.254
172.16.16.0 172.16.16.254
172.16.8.0 172.16.16.254
0.0.0.0 213.250.143.242

I'm not clear on whether you have internal routers, but if so they
should all have default routes to the gateway system as well as
specific routes to the local networks. The gateway IP for the local
PC's should be the router interface nearest them.
