Routing
These parameters are used to configure routing settings:
Act as router
– Enables IP forwarding between interfaces. Enabled by default.
Use Proxy ARP
– Enables proxy ARP. May be used with Viola M2M Router VPN. Disabled
by default.
S-NAT
These parameters are used to configure S-NAT (source network address translation) settings.
When enabled, private IP address used in local LAN is changed to GPRS interface IP
address. By default, this feature is enabled from all IP addresses (0/0) in eth0. This means,
that users connected to Arctic Ethernet can use and for example browse the web by using
Arctic as default router.
From IP
– Only S-NAT connections from the defined IP address are accepted. If defined with
wildcard (0/0), all IP addresses are handled the same way (only S-NAT connections are
allowed).
