I am able to connect my personal laptop to the SSID set up through the raspberry pi 4.
You forgot to mention which IP addresses are assigned to your laptop and your RaspPi.
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0. 192.168.0.1 0.0.0.0 UG 202 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 202 0 0 eth0
192.168.17.0 0.0.0.0 255.255.255.0 U 303 0 0 wlan0
Is this correct?
This says "the RaspPi has a default gateway behind the LAN, namely 192.168.0.1. This is where all 'Internet' requests will be routed to. It also connects to LAN on
192.168.0.*/24, and to WLAN on
Since you use the RaspPi as an AP on WLAN, you somehow need to connect it to your internet router (but didn't tell us how) and by this table you used the LAN for it; then if that is the case, it is correct.
You need to give the output of
ip addr on top of that to see which IP address it uses for
when I try to use the command
sudo tcpdump -i eth0 -v dst 192.168.0.57 and src 192.168.0.1 nothing happens
This says "capture all packets coming from the router (192.168.0.1) and going to 192.168.0.57, whatever that address is".
As the router is not going to send any packets from itself except for infrastructure services running on it, and your Laptop should be on the WLAN, so it should have an 192.168.17.? address (whatever it is, you didn't say), it's no surprise you don't see anything.
wireshark instead of
tcpdump, you get direct feedback and can adjust your filters.
If you want to inspect traffic from and to your Laptop, run
wlan0. Then the only additional traffic you'll see is that between the RaspPi and the Laptop, and that can only be causes by services running on the RaspPi (there shouldn't be too many of those).
If you want to filter, filter by your laptop's address (192.168.17.?) in a
src ... or dst ... fashion ("show me all packets to and from the laptop").
Note that packets from the laptop going to the internet won't have 192.168.0.1 as destination address, but the address of whatever you contact on the internet, and similarly in the reverse direction.
