I've moved house and internet provider + router, so this may be the source of the problem. My pi was working fine prior to this.

My pi (running raspian) has a static IP (on eth0), and I can ssh fine from within my network. However, I can't connect to the internet (i.e. ping google). Can someone point me to where to go from here?

Update:

pi@raspberrypi:~ $ ping 8.8.8.8
connect: Network is unreachable

pi@raspberrypi:~ $ ip r
192.168.1.0/24 dev eth0 proto dhcp scope link src 192.168.1.99 metric 202

pi@raspberrypi:~ $ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"

VERSION_ID="10"

static routers=192.168.1.1
static domain_name_servers=192.168.1.1

# It is possible to fall back to a static IP if DHCP fails:
# define static profile
#profile static_eth0
#static ip_address=192.168.1.23/24
#static routers=192.168.1.1
#static domain_name_servers=192.168.1.1

# fallback to static profile on eth0
#interface eth0
#fallback static_eth0

You have discovered one of the drawbacks of setting a Static IP address - You need to change it each time you change networks.

If you let the router do its job and assign via DHCP it would work automatically.

I recommend restoring normal network settings - See How to set up networking/WiFi

If REALLY must set a Static IP address you need to configure it from scratch for each new router. See How to set up Static IP Address

NOTE your original dhcpcd.conf is incomplete - you have not set a gateway for Ethernet.

To set a static gateway specify like the following, but use the values derived from your network, as described in the How to set up Static IP Address link.

   interface eth0
   static ip_address=10.1.1.30/24
   static routers=10.1.1.1
   static domain_name_servers=10.1.1.1

To restore to DHCP routing just remove (or comment out) ALL interface… entries i.e. containing static etc.

It looks like your dhcpd.conf is just like it was delivered, so I wonder how you set that static IP.

In any case, my scientific wild guess is that your new gateway router has a different address than at your old home. If you haven't done much customization of Raspbian, just flash a new copy onto your SD card. I think it'll work.

If you have done a bunch of customizing, undo what you did to set the static address, including specifically anything that refers to a gateway address. (If you have an extra SD card, perform the first test first, just to give yourself confidence that undoing the static address will work.)
