2.5.5 Firewall Rules
By default there are no rules on the new interface, so the firewall will block all traffic. This is ideal for a WAN, so is
safe to leave as-is. Adding services on the new WAN, such as VPNs, may require rules but those should be handled
on a case-by-case basis.
Warning:
Do not add any blanket “allow all” style rules on any WAN.
2.5.6 Gateway Groups
Gateway Groups do not control traffic directly, but can be used in other places, such as firewall rules and service
bindings, to influence how those areas use gateways.
For most scenarios it helps to create three gateway groups to start with:
PreferWAN
,
PreferWAN2
, and
LoadBalance
:
• Navigate to
System > Routing
,
Gateway Groups
tab
• Click
Add
to create a new gateway group
• Configure the group as follows:
Group Name
PreferWAN
Gateway Priority
Gateway for WAN on
Tier 1
, and WAN2 on
Tier 2
Description
Prefer WAN, fail to WAN2
• Click
Save
• Click
Add
to create another gateway group
• Configure the group as follows:
Group Name
PreferWAN2
Gateway Priority
Gateway for WAN on
Tier 2
, and WAN2 on
Tier 1
Description
Prefer WAN2, fail to WAN
• Click
Save
• Click
Add
to create another gateway group
• Configure the group as follows:
Group Name
LoadBalance
Gateway Priority
Gateways for WAN and WAN2 both on
Tier 1
Description
Prefer WAN2, fail to WAN
Note:
This performs connection-based load balancing, not per-packet load balancing.
