Site A got 100 subnets [login to view URL] to [login to view URL] There is a linux router on Site A with the IP address .1 of any subnet connected to eth0:1 to eth0:100. There is one single internet connection provided by another router [login to view URL] which is connected to eth1 of the linux router ([login to view URL]). The linux router on Site A should have a vpn connection to a linux router on Site B. All internet traffic from the Site A subnets needs to pass that vpn tunnel to Site B where it gets into the internet. The subnets are not allowed to access the other subnets except [login to view URL], where we got some services needed by all subnets. You need to configure: - the vpn tunnel (openvpn or something) - firewall rules (nftables) that deny access between the subnets - firewall rule (nftables) that allows access to [login to view URL] from any subnet - routing all subnets internet traffic through the tunnel to the internet - minimum (guaranteed) bandwidth for some of those subnets bi-directional (you must use upstream rules on routers on Site A and Site B for that) - basic QoS rules (realtime traffic like VoIP first) This is all theoretically! We want you to provide us the tools and commands we need to get it running.

Hello! I would like to help you with this task. I suggest you to use OpenVPN, it's strong, flexible and good VPN protocol. Also if you want I can suggest you using pfSense instead of Linux command line router. If you have so many networks, it's much easier to manage them through pfSense web interface. pfSense is very performance, and very flexible router. It can be installed on any x86 PC. Of course I can help with hardware if needed. But of course it's not mandatory, we can do it on usual command line Linux. About my experience: I have big experience with network administration (VLAN, SNAT, DNAT, iptables, iproute2, multiWAN, tcpdump...), managed switches, routers... Big experience with virtualization systems: VMWare ESXi, vCenter, MS Hyper-V, Proxmox VE. Backups and replications for virtualization - Veeam B&R. A lot of experience with OpenVPN servers/clients. TUN\TAP networks, complex routing for separate clients. Serial connection 2,3 servers for more security. OpenVPN over IPv6 and other... Extensive experience with pfSense routers. I use it in every office in my main job, in my own office, as router on rented servers. What I did with pfSenses: DHCP, DNS, DyDNS, SNAT, DNAT, 1:1 NAT, Destination\Source routing, Carp (2 hardware pfSenses in failover mode), MultiWAN, gateway groups (failover and load balancing), VLANs, a lot of experience with OpenVPN servers\clients on pfSense. Hope for cooperation! Thank you!
