Hello everyone, subject as I have established a BGP session with my provider and the classes seem to propagate correctly (it says my provider) and what he says RIPE! i can reach also get to the ip .1 (configured on a loopback interface of the router bgp neighbor and used for) from another line (outside) ...
show ip bgp neighbors ip_fornito_da_provider advertised-routes BGP table version is 351730, local router ID is xx.yy.zz.1 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale Origin codes: i - IGP, e - EGP, ? - incomplete

Total number of prefixes 1
gigabit0/0 is directly connected to Internet with multiple ip address (1 pubblic for going internet and 1 private for making BGP) my provider says to me to do this ! :O (outgoing interface on the Internet)
GigabitEthernet0/0 is up, line protocol is up Internet address is pubblic_ip_of_upstream provider/24 Broadcast address is 255.255.255.255 Address determined by non-volatile memory MTU is 1500 bytes Helper address is not set Directed broadcast forwarding is disabled Secondary address 192.168.100.1/24 <----------- ip for making bgp Outgoing access list is not set Inbound access list is not set
Loopback0 is up, line protocol is up Internet address is my_first_ip_/32 Broadcast address is 255.255.255.255
this is my static route table (without full routing table of BGP)

Gateway of last resort is not set
xx.yy.0.0/16 is variably subnetted, 30 subnets, 5 masks <------- class B of my public network also if i've received from Ripe a /21 S xx.yy.zz.0/21 is directly connected, Null0 <------ my /21 aa.bb.cc.0/32 is subnetted, 1 subnets <------ neighbor of provider S aa.bb.cc.dd [1/0] via 192.168.100.2
this is the problem now ... I would give my public interface directly on top of the router ....
so i can connect to my gigabit ethernet0/1 and assign pubblic address aa.bb.cc.4 255.255.248.0 gateway aa.bb.cc.1 and able to internet with that address so i can connect an ASA that will handle the public through NAT and PAT
You can do such a thing? I apologize if it's a simple thing but it is the first BGP configuration and are a bit in trouble .. I searched around but have not found anything like what I'm looking for ... thanks to all those who want to answer and help me
