We have a private WAN IP network (WAN: 10.255.255.0/28) consisting with five different subnets each with their own IP (LAN)addressing space.
LAN 1= 172.16.0.0/16
LAN 2= 10.1.7.0/22
LAN 3= 172.28.130.0/23 (VLAN)
LAN 4= 172.17.0.0/16
LAN 5= 10.169.254.0/24
I need to be able connect LAN 5 to LAN 3 (VLAN) - and route all Internet traffic from LAN 3 (VLAN) to a gateway on LAN 5 - while at the same time restrict LAN 5 from connecting to any of the other LANs.
The biggest problem I can't get my arms around is all of the 10.x networks involved. We also employ EIRGP on each router.
