On the ccr1036 when i use the web proxy feature and ram as cache the cache cannot be cleared without doing a reboot and the proxy slows significantly when it is full. Another main problem is that when i only allow from ip address from a LAN network even outside ip addresses are able to use the proxy which has resulted in a lot of bot advertisement traffic. I’ve had to use whitelists from the firewall but it breaks a lot of websites.
My ISP uses a 1-2-1 NAT on my router so it gets a LAN address. There is no way around this however the ip address my LAN devices use is a different network (they are part of 2 networks).
