HanoiCTT HanoiCTT HanoiCTT HanoiCTT Networking Academy lab: routing-004a date: IP addressing: subnetting using two major networks: /16 and /16. Routing protocol: EIGRP, AS=234, hello interval=5, hold time=20. Food ACL: Disallow NET1NET4, except HTTP+TELNET one-way to NET1 which is allowed. ip http server. Gold ACL: Disallow NET2NET3, except HTTP+TELNET two-way which is allowed. ip http server. Iron and Coal: Routing: no auto-summary (because of discontinuous network). ACL (line vty 0 4): Deny all TELNET to these routers, except TELNET from NET3+NET4 which is allowed. Dynamic NAT: both Wood and Stone. DHCP: Wood is DHCP server (for NET5) and Iron is using ip helper-address on the Ethernet port. Static NAT: Stone ip nat inside source static tcp lo2_address Stone ACL: INTERNET cannot initialize TCP to the inside network (except to lo2_address). Option: EIGRP authentication, key=123, password=abc. Note for ACL: all connections are allowed by default policy.
