[srslte-users] No Internet Connection on Phone

[Bennett Gogarty]

I have IP forwarding enabled. I had the first of the IP tables already in
there. I added the other two. Now it seems I can ping 8.8.8.8, but it's
really slow. I've only gotten two responses back in about 10 minutes and
the phone still doesn't get internet access. Are there any settings on the
phone that might need to be changed?
