I have two ISPs and I need traffic from my servers (web, email, vpn) go for ISP1 and web browsing for ISP2. I think I have to put a router and use PBR for redirect traffic to ISP1 or ISP2, and use PAT for ISP2. I have a lan with about 75 users and an ISP1 throughput of about 3 Mbps and ISP2 of 8 Mbps. Which router I have to choose? Can be enough an 881? Or better 1811?
