lab 17-10-2016

[Marco Bonola < >]

Dear students,

please find attached:

1) topo.png: topology of the lab done in class today 17/10/2016
2) r1_1, r2_1, r3_1, r4_1: cisco routers configuration

I also remind you the following linux commands:
0) ip link set XXX up (bring device XXX up)
1) ip a flush dev XXX (delete all addresses on device XXX)
2) ip a add XXX/YY dev ZZZ (add ip address XXX/YY on device ZZZ)
3) ip r add default via XXX  (add default gateway via XXX)
4) ip r add XXX/YY via ZZZ  (add next hop to XXX/YY)
5) iptables -t nat -A POSTROUTING -o XXX -j MASQUERADE (dinamically NAT 
all packet going out through dev XXX)
6) echo 1 > /proc/sys/net/ipv4/ip_forward (enable IP forwarding)

As homework I suggest you to re-configure the linux machines.

On ubuntu-server-4 remember to:
1) add a second adapter (type NAT)
2) enable IP forwarding
3) enable dynamic NAT
4) manually add all required routers

Ciao
Marco
