Appropriate firewall
rules
To allow remote access to the SpeedTouch
TM
610 web pages from the WAN, you must
add following rules:
• To t he s ink c hain :
The rule allows incoming traffic from the WAN to the SpeedTouch
TM
610 web
host.
The rule is inserted after the first two rules (index=0 and index=1) as none of the
two rules apply to traffic coming from any WAN interface. However, make sure
(as in the example) to insert the rule before the last rule (which drops all traffic
not blocked by any preceding rule).
Note If you want to allow remote access to the SpeedTouch
TM
610 web pages in a
Bridged Ethernet Packet Service scenario, you must add the rule mentioned
above with index=0 (i.e. the added rule becoming the first one) to avoid that
the traffic coming from the WAN Bridge port and destined for the
SpeedTouch
TM
610 web host is dropped.
• To the source chain:
The rule allows outgoing traffic from the SpeedTouch
TM
610 web host to the
WAN. It is added after the first rule concerning all traffic towards the LAN as it
has no concern with it, but before the last rule (which drops all traffic not blocked
by any preceding rule).
The added rules will allow any user on the WAN to contact the SpeedTouch
TM
610 web
pages and browse them after authentication.
Refinements of the
rules
However, if needed, the rules can be fine-tuned to allow only traffic coming from/going
to a particular Packet Service interface, or even (additionally) restrict allowed traffic to
a range of IP addresses.
The example below shows the rules to add in case a separate management PVC (called
IPoA) is used with the Routed IPoA Packet Service configuration in the 192.6.11.x/24
range of IP addresses. In this setup only remote hosts with an IP address in the range of
192.6.11.1 to 192.6.11.254 with an IP connection to the SpeedTouch
TM
610 via the IPoA
WAN interface are allowed to contact the SpeedTouch
TM
610 web pages.

SpeedTouch
TM
610 CLI Reference Guide.
