I am totally new to Juniper routers. I have used mostly had Netgear and Linksys routers so I am unfamiliar with the terminology. I am a total noob so bear with me. I have an SRX300 and am trying to set it up on a simple home network. I bumbled my way thru using Putty. I set up set up DHCP and computers get a network address just fine. For the life of me I cannot get the internet working!! I have spectrum and a dynamic IP address. I can ping 8.8.8.8 and the computers show the online icon. I can't ping any websites or visit them. I've been accessing the router thru SSH and the web interface thru Firefox. Here's my config file. Please help
