Name Servers
DNS 1
Dotted IP addresses for Domain Name Servers 3 . [192.168.0.1]
The name servers can be on the LAN, or accessible via the
Gateway. Typically, the gateway IP address can be used as
this will proxy the DNS requests.
DNS 2 Secondary DNS server. [255.255.255.255]
Proxy Server
The ip.buffer can talk to the outside world through a proxy server. The proxy servers can
be used when delivering to HTTP POST, FTP Push, and Email Push, and TCP Push
4 .
Type of proxy
“
None (no proxy)
” - communicate directly.
“
HTTP/1.1 using CONNECT
” - communicate using the HTTP
proxy protocol 5 .
“
SOCKS 5
” - communicate using SOCKS version 5.
“
SOCKS 4a
” - communicate using SOCKS version 4a.
[None (no proxy)]
Server
The name, or IP address, of the proxy server. (When using HTTP
Proxy protocol: not a URL, so no 'http:', just an plain
address or name)
[blank]
TCP Port
The TCP port that the proxy server is listening on. The normal
ports are 8080 when using HTTP Proxy, and port 1080
when using SOCKS 5 or SOCKS 4a. [blank]
Username The username, if needed, for the proxy server. [blank]
Password The password, if needed, for the proxy server. [blank]
No Proxy For
A list of explicit, or wildcard 6 , addresses or names to skip proxy
for. Typically you enter the names or addresses of local
machines in this list to prevent them needlessly going via
the proxy. Separate the list with commas, semicolons, or
spaces.
e.g. “192.168.*, *.scannex.com, *.scannex.co.uk” [blank]
If in doubt about the proxy settings then the IT department usually will know!
3 DNS name-to-IP entries are cached for a maximum of 5 minutes. The DNS server can specify a
shorter time in the time-to-live field of the DNS response.
4 Stale connections can be a problem with TCP push over a proxy. You should ensure the proxy
server uses keep-alives so it knows if the link to the far end has been broken.
5 Do not confuse this with the delivery/destination type. The HTTP Proxy protocol can be used for
delivering by FTP push and by email (because the HTTP protocol is used for talking to the proxy
only).
6 “*” = anything, “?” = any character.
