The IP-addresses of the VPN modem are not pinged

Hello! An Internet modem is connected to the FastEthernet4 interface of the Cisco 881-SEC-K9 router, a VPN modem is connected to the FastEthernet1 interface, and an unmanaged LAN switch is connected to the FastEthernet0 interface. It is necessary to that the computer connected to the switch have the Internet and access certain resources via a VPN modem. The IP address of the Internet modem is 10.41.196.2 (DHCP is enabled on the modem), the VPN modem is 172.26.66.171. The Cisco configuration is as follows:

There is Internet on the computers of the local network. The IP address 172.26.66.173 of the Vlan30 port bound to the FastEthernet1 interface to which the VPN modem is connected is pinged from the LAN computer (if the mask of the additional IP address of the computer 172.26.66.177 is  255.255.255.248, if the mask is 255.255.255.0, then no). The IP addresses of the 172.266.66.XXX network and the IP addresses specified in the Cisco "ip route" commands are pinged from the Cisco console. But all these addresses are not pinged from the LAN computer, only 172.266.66.173 (Vlan30 address). I tried to enable routing on my computer:

route ADD 10.128.217.12 255.255.255.255 172.26.66.173

Nothing has changed, the address 10.128.217.12 did not ping after that. Question: what should I do to make the IP addresses of the 172.26.66.xxx network and those specified in the "ip route" commands on Cisco "visible" from the computer?
