WAN Link Management Depending on your hardware model, WAN links can be made up of either Wireless Wide Area Network (WWAN), Wireless LAN (WLAN), Ethernet or PPP over Ethernet (PPPoE) connections. Please note that each WAN link has to be conﬁgured and enabled in order to appear on this page.

Page 31 NB3700 User Manual 3.8 We recommend to use the permanent operation mode for WAN links in general. How- ever, in case of time-limited mobile tariﬀs for instance, the switchover mode might be applicable. By using the distributed mode, it is possible to distribute outgoing traﬃc over multiple WAN links based on their weight ratio.

Page 35: Ethernet
NB3700 User Manual 3.8 5.3.2. Ethernet NB3700 routers ship with an Ethernet switch (ETH1-ETH5) which can be linked via M12 connectors. ETH1 usually forms the LAN1 interface which should be used for LAN purposes. Other interfaces can be used to connect other LAN segments or for conﬁguring a WAN link.
Page 36: Ethernet Link Settings
NB3700 User Manual 3.8 Ethernet Link Settings Figure 5.7.: Ethernet Link Settings Link negotiation can be set for each Ethernet port individually. Most devices support auto-negotiation which will conﬁgure the link speed automatically to comply with other devices in the network. In case of negotiation problems, you may assign the modes manually but it has to be ensured that all devices in the network utilize the same settings then.
Page 37: Vlan Management
NB3700 User Manual 3.8 VLAN Management NetModule routers support Virtual LAN according to IEEE 802.1Q which can be used to create virtual interfaces on top of an Ethernet interface. The VLAN protocol inserts an additional header to Ethernet frames carrying a VLAN Identiﬁer (VLAN ID) which is used for distributing the packets to the associated virtual interface.

Once a SIM card has been inserted, assigned to a modem and successfully unlocked, the card should remain in state ready and the network registration status should have turned to registered.
Page 42 NB3700 User Manual 3.8 Conﬁguration A SIM card is generally assigned to a default modem but might be switched, for instance if you set up two WWAN interfaces with one modem but diﬀerent SIM cards. Close attention has to be paid when other services (such as SMS or Voice) are operating on that modem, as a SIM switch will naturally aﬀect their operation.

NB3700 User Manual 3.8 5.4. ROUTING 5.4.1. Static Routes This menu shows all routing entries of the system. They are typically formed by an address/netmask couple (represented in IPv4 dotted decimal notation) which specify the destination of a packet. The packets can be directed to either a gateway or an interface or both.
Page 63: Static Route Flags
NB3700 User Manual 3.8 Parameter Static Route Conﬁguration Netmask The subnet mask which forms, in combination with the des- tination, the network to be addressed. A single host can be speciﬁed by a netmask of 255.255.255.255, a default route corresponds to 0.0.0.0.

NB3700 User Manual 3.8 5.4.2. Extended Routing Extended routes can be used to perform policy-based routing, they generally precede static routes. Figure 5.21.: Extended Routing In contrast to statis routes, extended routes can be made up, not only of a destination address/netmask, but also a source address/netmask, incoming interface and the type of service (TOS) of packets.

Figure 5.22.: Multipath Routes At least two interfaces have to be deﬁned to establish multipath routing. Additional interfaces can be added by pressing the plus sign.
Page 67: Mobile Ip
Eﬀectively, any WAN link switch causes very small outages during switchover while keeping all IP connections alive. Moreover, NetModule routers also support NAT-Traversal for mobile nodes running behind a ﬁrewall (performing NAT), which makes mobile nodes even there accessible from a central oﬃce via their home address, and thus, bypassing any complicated VPN...

Page 70: Quality Of Service
NB3700 User Manual 3.8 5.4.5. Quality Of Service NetModule routers are able to prioritize and shape certain kinds of IP traﬃc. This is currently limited on egress, which means that only outgoing traﬃc can be stipulated. The current QoS solution is using Stochastic Fairness Queueing (SFQ) classes in com- bination with Hierarchy Token Bucket (HTB) qdiscs.

Page 72: Multicast
NB3700 User Manual 3.8 5.4.6. Multicast NetModule routers ship with an IGMP proxy which is able to maintain multicast groups on a particular interface and distribute incoming multicast packets towards the down- stream interfaces on which hosts have joined the groups.
Page 73: Firewall
NB3700 User Manual 3.8 5.5. FIREWALL 5.5.1. Administration NetModule routers use Linux’s netﬁlter/iptables ﬁrewall framework (see http://www. for more information) which supports stateful inspection, that is, grant- netfilter.org ing the same permissions for inherited connections within an IP session (e.g. FTP which builds up a control and data connection).
Page 74: Rules
NB3700 User Manual 3.8 5.5.3. Rules In general, the ﬁrewall is set up of a range of rules which control each packet’s permis- sion to pass the router. Please note that the rules are processed by order, that means traversing the list from top to bottom until a matching rule is found. Packets which are not matching any of the rules conﬁgured will be ALLOWED.

Page 85: Ipsec
NB3700 User Manual 3.8 5.6.2. IPsec IPsec is a protocol suite for securing IP communications by authenticating and encrypt- ing each packet of a communication session and thus establishing a secure virtual private network. IPsec includes various cryptographic protocols and ciphers for key exchange and data encryption and can be seen as one of the strongest VPN technologies in terms of security.

Page 87: Ipsec Conﬁguration
NB3700 User Manual 3.8 Administration This page can be used to enable/disable IPsec, you may also specify whether NAT- Traversal should be used. NAT-Traversal is mainly used for connections which traverse a path where a router modiﬁes the IP address/port of packets. It encapsulates packets in UDP and therefore requires a slight overhead which has to be taken into account when running over small- sized MTU interfaces.
Page 88 IKE Authentication NetModule routers support IKE authentication through pre-shared keys (PSK) or certiﬁ- cates within a public key infrastructure. Extended Authentication (XAUTH) leverages RADIUS-like authentication and can be used to apply user level access control over IPSec.

Page 91: Pptp
NB3700 User Manual 3.8 5.6.3. PPTP The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks between two hosts. PPTP is easy to conﬁgure and widely deployed amongst Microsoft Dial-up networking servers. However, due to its weak encryption algorithms, it is nowadays considered insecure but it still provides a straightforward way for establishing tunnels.

Page 94: Gre
NB3700 User Manual 3.8 5.6.4. GRE The Generic Routing Encapsulation (GRE) is a tunneling protocol that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links over IP. GRE is deﬁned in RFC 1701, 1702 and 2784. It does not provide encryption nor authorization but can be used on an address-basis on top of other VPN techniques (such as IPsec) for tunneling purposes.
Page 95: Dial-In
NB3700 User Manual 3.8 5.6.5. Dial-In On this page you can conﬁgure the Dial-In server in order to establish a data connection over GSM calls. Thus, one would generally apply a required service type of 2G-only, so that the modem registers to GSM only. Naturally, a concurrent use of outgoing WWAN interfaces and Dial-In connection is not possible.
