Config. Cisco Routers

First issue: standard NAT will do.

inglish, huh ? mai bine explicai in romana, era mai inteligibil.

ce model de router? il configurezi din interfata web sau CLI ?

First issue: standard NAT will do.
Second issue: "ip nat inside source static tcp 1.2.3.4 80 2.3.4.5 80" will redirect any incoming tcp packets to 2.3.4.5 to 1.2.3.4 on port 80.

Good afternoon!!

I have some questions about configuring a Cisco
Router.Where can I find some answers??

I want two thinks:
1)What is the command to forward DNS information from
a computer in private network to a DNS server????

What for????  ilogic operation :(

2)I have a computer that is Mail&Web server and I
have to use just one external(outside) IP Address for
all computers in 3 different private(internal)
networks. And I want to forward traffic destinated for
that Server from router to it(just ports for that
applications:80...).I don't know what I must use or
how can I do.

this is NAT

interface A1
ip add x.x.x.x y.y.y.y
ip nat outside

interface A2
ip add a.a.a.a b.b.b.b
ip nat inside

access-list X permit PRIVATE CLASS + wildcard
ONE OF IP ADDRESS IS FROM PRIVATE CLASS!!!!!!!!!!!
can I use ACL??
but how??what
commands??Can you help me??

Yes u can use!!!!
access-list X permit X.X.X.X wildcard

"set nat entry add 2.3.4.5 80 tcp" , daca vrei sa fie independent de adresa externa.
