I have two vlans on my network, vlan 2 of 10.201.0.0/16 and vlan 3 of 10.50.0.0/24, however, traffic on vlan 2 on which the LAN (eth0) interface is directly connected to can access internet and vlan 3 which is added to (eth0) as an alias with the IP address on the 10.50.0.0/24 network is not accessing internet.
From the vlan 3 network, on the checkpoint, I cannot ping any client machine on the same network, however from the switch directly connected to the checkpoint firewall can ping the firewall and from firewall and computers on vlan 2 can ping each other.
I have permitted/accepted all traffic on both networks on 10.201.0.0/16 and 10.50.0.0/24 to any/internet. but when I ping 220.127.116.11 from a computer on vlan 3, I get an error of "address spoofing". see the image of the error log attached .
I will appreciate your support on this.
