Hi Brandon, Thanks for your prompt response. It's hard to get access to those remote LC PC because those doesn't have even any display.
I found (by googling) some cheep 3G/4G router is capable of doing this as SNAT
SNAT This function transparently passes on the incoming data traffic from Internet or VPN connections to the LAN. In other words, all data packets going to the LAN are assigned the IP address of the router as the sender address. This means that none of the LAN subscribers need the router as a “gateway”. This is a considerable advantage when integrating remote maintenance into existing network structures as it means that these structures do not need to be changed....
configuration is attached but here is
! interface Cellular0 ip address negotiated ip nat outside no ip virtual-reassembly in encapsulation slip dialer in-band dialer idle-timeout 0 dialer string lte dialer watch-group 1 async mode interactive ! interface Cellular1 no ip address encapsulation slip shutdown ! interface wlan-ap0 no ip address ! interface Vlan1 ip address 192.168.16.1 255.255.255.0 ip nat inside ip virtual-reassembly in ! interface Async0 no ip address encapsulation scada ! interface Async1 no ip address encapsulation scada ! ! ip forward-protocol nd ! no ip http server no ip http secure-server ! ip nat inside source static tcp 192.168.16.11 80 interface Cellular0 8888 ip nat inside source static tcp 192.168.16.12 5900 interface Cellular0 5900 ip nat inside source static tcp 192.168.16.13 5900 interface Cellular0 5910 ip nat inside source list 101 interface Cellular0 overload ip route 0.0.0.0 0.0.0.0 Cellular0 ! dialer watch-list 1 ip 184.108.40.206 0.0.0.0 !-- this is generating bogus trafic to keep the cellular 0 interface up. dialer-list 1 protocol ip permit ipv6 ioam timestamp ! ! access-list 101 permit ip any any !

I have configured a Cisco IR829GW (network diagram attached), so that, I can access remote site (LAN hosts) from my home PC. Cisco IR829GW is a 4G router. My SIM card subscriber providing DHCP IP to the Celllular interface of IR829GW.
Remote site LAN hosts are having two category
(1) host TCP/ IP is properly configured. Meaning IP, netmask and default gateway are configured (2) host TCP/ IP is not properly configured. Meaning default gateway is not configured.
Hosts from category 1 can access internet and those are also accessible from internet (from home PC). But host from category 2, neither can access internet nor can be accessed from internet (home pc). These hosts are running UltraVNC (TCP/5900), by default. I would like to access to those PCs remote desktop from my home PC. Is it possible? If yes, could someone kindly advise me.
I have also attached configuration file here.
Thanks you in advance.
