TCP Port Mapper in Proxy mode: how redirect all traffic to the specified host:port.

TCP Port Mapper

by Vitaly, Friday, July 31st, 2015

When TCP Port Mapper (tcpportmap) acts as a proxy (ProxyMode has one of the values: HTTP, CONNECT, SOCKS4 or SOCKS5), then MapToHost and MapToPort can be used to forward all traffic to the specifed host:port.

For example, let ProxyMode=CONNECT and TCP Port Mapper has received this command from the client:

CONNECT www.google.com:80 HTTP/1.1
  1. If MapToHost=127.0.0.1, MapToPort=8080 then TCP Port Mapper will establish connection to 127.0.0.1:8080.
  2. If MapToHost=127.0.0.1, MapToPort is not specified (or zero) then TCP Port Mapper will establish connection to 127.0.0.1:80.
  3. If MapToHost is not specified (or empty), MapToPort=8080 then TCP Port Mapper will establish connection to www.google.com:8080.
  4. If the both MapToHost and MapToPort are not specified then TCP Port Mapper will establish connection to www.google.com:80.

IPv6 support for TCP Port Mapper

TCP Port Mapper

by Vitaly, Friday, June 26th, 2015

TCP Port Mapper 1.70 released.

Now IPv6 addresses can be used in all settings: ListenIP, MapToHost, MapArray, MapFromFile, MapFromUrl etc.

It is preferred to enter IPv6 addresses, enclosed in square brackets. That allows to extract the Port from the IPv6:Port.
Example of the IPv6 address: [2001:4860:4860::8888].

If the ListenIP setting is not specified (or ListenIP=ANY) you can set SrvIPv6=Yes.
That allows to force listening incoming IPv6 connections.

If the both IPv4 and IPv6 addresses are exist for the destination host, TCP Port Mapper will use IPv4 address. To force using IPv6 address you can set: CntIPv6=Yes.

Resolve External IP

Web Proxy Checker

by Vitaly, Wednesday, July 1st, 2015

URL to resolve IPv4 address:

http://ipv4.test-ipv6.com/ip/?callback=_jqjsp&asn=1&testdomain=test-ipv6.com&testname=test_asn4

Response (IPv4):

_jqjsp({"ip":"xxx.xxx.xxx.xxx","type":"ipv4","subtype":"","via":"","asn":"yyyyy","asn_name":"Provider Name,US","asnlist":"yyyyy","padding":""})

Extract IPv4 regular expression:

\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}

URL to resolve IPv6 address:

http://ipv6.test-ipv6.com/ip/?callback=_jqjsp&asn=1&testdomain=test-ipv6.com&testname=test_asn6

Response (IPv6):

_jqjsp({"ip":"xxxx:x:xxxx:xxx:xxxx:xxxx:xxxx:xxxx","type":"ipv6","subtype":"Teredo","via":"","padding":""})

Extract IPv6 regular expression:

([0-9a-fA-F]{1,4}:){7,7}[0-9a-fA-F]{1,4}|([0-9a-fA-F]{1,4}:){1,7}:|([0-9a-fA-F]{1,4}:){1,6}:[0-9a-fA-F]{1,4}|([0-9a-fA-F]{1,4}:){1,5}(:[0-9a-fA-F]{1,4}){1,2}|([0-9a-fA-F]{1,4}:){1,4}(:[0-9a-fA-F]{1,4}){1,3}|([0-9a-fA-F]{1,4}:){1,3}(:[0-9a-fA-F]{1,4}){1,4}|([0-9a-fA-F]{1,4}:){1,2}(:[0-9a-fA-F]{1,4}){1,5}|[0-9a-fA-F]{1,4}:((:[0-9a-fA-F]{1,4}){1,6})|:((:[0-9a-fA-F]{1,4}){1,7}|:)

IPv6 support for DNS Server

DNS Server

by Vitaly, Friday, June 12th, 2015

DNS Server 1.49 has been released.

  1. Added the ability to send requests to the IPv6 DNS servers. Now DNSHost, DNSHost2 and FromIP settings can contain IPv6 addresses (read Help for more info).
    Example (using Google IPv6 DNS):

    DNSHost=2001:4860:4860::8888
DNSHost2=2001:4860:4860::8844

  2. Added the ability to listen incoming DNS requests on IPv6. SrvIP and SrvIP2 settings can contain IPv6 addresses.
    If SrvIP is not specified or it contains Any value then you can force using IPv6 by specifying:

    
SrvIPv6=Yes

User Agents

General

by Vitaly, Monday, April 27th, 2015

“User-Agent” HTTP header allows to identify Internet Explorer version.

Look the following article to learn more about Internet Explorer user-agent strings: Understanding user-agent strings.

Pay attention to the compatibility changes in IE 11:

  • The compatible (“compatible”) and browser (“MSIE”) tokens have been removed.
  • The “like Gecko” token has been added (for consistency with other browsers).
  • The version of the browser is now reported by a new revision (“rv”) token.
