Is there anyone on this forum that can shed some light on how to make changes to the Juniper SRX300 without bricking the Comcast setup that was pre-configured at turn-up?
Hello vstbna and welcome to forums,
I apologize for any frustration this has caused you but unfortunately I do not have any information on post turn-up configurations. Below is a link to the Hardware Guide for this model firewall. With this information you may find what is needed to configure your firewall. I hope this information helps.
I apologize but I am unclear of your request. You can always post or message me in the business forums or you can call 24/7 at 1-800-391-3000. Does this answer your question?
