My working company has this router (Cisco RV042G Gigabit Dual WAN VPN Router) and it has the IP
192.168.1.1 with subnet mask
255.255.255.0. It has 3 devices directly connected to its LAN ports, an ASUS access point
192.168.1.245, a D-Link access point
192.168.1.246 and a network printer
I have setup the VPN (PPTP) in the Cisco router in the IP range of
192.168.1.253 - 192.168.1.254. And this range is excluded from the Cisco router DHCP range.
From my home computer (physical line directly connected to the modem), I can connect to the company Cisco router successfully and gets assigned the IP
192.168.1.253. I can ping the Cisco router and the network printer without any problem. However, I cannot ping the two access points and cannot access their web admin interface.
I try to ping them from the Cisco router and find that they can respond the ping request. So I can confirm that the Cisco router can actually reach them. Also, other computer hosts in the company can access the internet through these two access points without any problem. And they can ping and access the web admin interface of these two access points.
I also tried to turn off the firewall in the Cisco router to make sure it's not the cause but it still does not solve the problem.
So why can't my home computer ping and access the web admin interface of the access points when it's connected by VPN?
