How to use external open source caching server
Sometimes admin want to control users HTTP requests through custmized ACL's or other scripts.
Mikrotik can be used as PPPoE server where all PPPoE or clients on 192.168.0.0/23 network are connected with Mikrotik directly through LAN.
Mikrotik with 3 interfaces
- LAN (for clients)
- WAN (for Internet)
- eth1 (for Squid)
Mikrotik simple view
Squid have 2 type of networks
- LAN IP Address 192.168.100.1/24 without any gateway or route address.
- Just for LAN connectivity with Mikrotik eth1 with 192.168.100.2/24 IP Address
- PPPoE conection for Internet throw Mikrotik 'but' different IP Address 192.168.12.2 (normal clients IP address 192.168.0.0/23)
Internet setup for Squid
Squid Internet access is working
Time to route clients traffic to address 192.168.100.1 with clients on IP's with 192.168.0.0/23 range
Disable NAT ( IP / Firewall / NAT / masquerade srcnat 192.168.0.0/23
When normal client request for Internet to Mikrotik then Mikrotik all LAN network 192.168.0.0/23 passthrow to Squid 192.168.100.1 direct without any delay.
Example: Any request from 192.168.0.0/23 network (with routing mark client), Mikrotik route this request to 192.168.100.1, and if another network request then Mikrotik route this request to WAN route 192.168.11.1.
