I have rasp pi 3 and I purchased this usb ethernet adapter:

https://www.amazon.co.uk/gp/product/B00M77HLII/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

The device was detected by the pi without me doing anything and comes up as eth1. Initially it was using a dynamic ip address from my dhcp server, but I changed the config of /etc/dhcpcd.conf as follows:

# Example static IP configuration:
interface eth1
static ip_address=192.168.4.10/24
static ip6_address=fd51:42f8:caae:d92e::ff/64
static routers=192.168.4.1
#static domain_name_servers=192.168.0.1 8.8.8.8 fd51:42f8:caae:d92e::1

I have an ethernet cross-over cable from the eth1 port to an old laptop running windows 7 configured with:

IP: 192.168.4.1 subnet mask: 255.255.255.0

From the Windows laptop I can ping 192.168.4.10 (IP of pi eth1) and get a success response. But when I ping from the pi to 192.168.4.1 it doesn't work:

i@raspberrypi:~ $ ping 192.168.4.1
PING 192.168.4.1 (192.168.4.1) 56(84) bytes of data.
^C
--- 192.168.4.1 ping statistics ---
9 packets transmitted, 0 received, 100% packet loss, time 8328ms

Am I missing some config on the pi? How can I fix this.

I want to be able to ping the Windows laptop from the pi.

Current pi networking:
