A2. Yes, the ADSL routers support multiple WAN and LAN interfaces. Originally, the web GUI is designed for normal end-users. Some of functions need to configure via CLI command set.
- Multiple WAN interface: you can create via web GUI or CLI

- Multiple NAT: only created via CLI

Q3. Dose router supports Multiple VPN tunnel pass through?
A3. In such environment, router supports multiple VPN tunnels pass through.
- PC1 (VPN-IPsec) <--> router <--> Internet <--> VPN servers
- PC can create multiple tunnels with different servers.
But in two PCs in LAN environment, the second PC cannot initial to establish a tunnel if PC1 has established a tunnel already. Because the returned packet from VPN server can not be forwarded correctly to the initial PC, returned packet from WAN site carries the same port and same destination IP address.
