Connecting from outside into server in LAN?

Hello,
I have installed ejabberd 1.1.2 onto one of servers in LAN in our company. Its name is "srvis03" and it has IP 10.0.2.3. So I have accounts like "admin@srvis03" etc. Everything works fine from workstations in LAN (we use Miranda and PSI). But then I come home...
In our ADSL modem configuration we set redirecting of inbound connection 5222/tcp to "srvis03". Now I am trying to connect from home. It should work, you may say. Well, it doesn't.
Miranda pops up with small window. Its heading is "Jabber error" and its content is "host-unknown: (null)".
On every connection attempt ejabberd writes to ejabberd.log these two lines (and nothing more):

=INFO REPORT==== 2007-02-20 17:22:40 ===
I(<0.223.0>:ejabberd_listener:90): (#Port<0.257>) Accepted connection {{***HOME IP***},1068} -> {{10,0,2,3},5222}

In Miranda Jabber plugin I've set up:

Username: admin
Password: ***ADMIN PASSWORD*** (it is correct, I am sure)
Login server: ***COMPANY IP***
Port: 5222
That's all. No SSL, no TLS.

I have also turned on verbose logging in Miranda network section. Here is what I get when I attempt to connect to company's ejabberd server:

And here is content of our ejabberd.cfg:

% $Id: $

%override_acls.

% Users that have admin access. Add line like one of the following after you
% will be successfully registered on server to get admin access:
{acl, admin, {user, "admin"}}.

% Blocked users:
%{acl, blocked, {user, "test"}}.

% Local users:
{acl, local, {user_regexp, ""}}.

% Another examples of ACLs:
%{acl, jabberorg, {server, "jabber.org"}}.
%{acl, aleksey, {user, "aleksey", "jabber.ru"}}.
%{acl, test, {user_regexp, "^test"}}.
%{acl, test, {user_glob, "test*"}}.

% Everybody can create pubsub nodes
{access, pubsub_createnode, [{allow, all}]}.

% Only admins can use configuration interface:
{access, configure, [{allow, admin}]}.

% Every username can be registered via in-band registration:
% You could replace {allow, all} with {deny, all} to prevent user from using
% in-band registration
{access, register, [{allow, all}]}.

% After successful registration user will get message with following subject
% and body:
%{welcome_message,
% {"Welcome!",
% "Welcome to Instant Messaging server localhost. "
% "For information about ejabberd visit http://www.process-one.net/"}}.
% Replace them with 'none' if you don't want to send such message:
{welcome_message, none}.

% List of people who will get notifications about registered users
%{registration_watchers, ["admin1@srvis03",
% "admin2@srvis03"]}.

% Only admins can send announcement messages:
{access, announce, [{allow, admin}]}.

% Only non-blocked users can use c2s connections:
{access, c2s, [{deny, blocked},
{allow, all}]}.

% Set shaper with name "normal" to limit traffic speed to 1000B/s
{shaper, normal, {maxrate, 1000}}.

% Set shaper with name "fast" to limit traffic speed to 50000B/s
{shaper, fast, {maxrate, 50000}}.

% For all users except admins used "normal" shaper
{access, c2s_shaper, [{none, admin},
{normal, all}]}.

% For all S2S connections used "fast" shaper
{access, s2s_shaper, [{fast, all}]}.

% Admins of this server are also admins of MUC service:
{access, muc_admin, [{allow, admin}]}.

% All users are allowed to use MUC service:
{access, muc, [{allow, all}]}.

% This rule allows access only for local users:
{access, local, [{allow, local}]}.

% Authentication method. If you want to use internal user base, then use
% this line:
{auth_method, internal}.

% For LDAP authentication use these lines instead of above one:
%{auth_method, ldap}.
%{ldap_servers, ["srvis03"]}. % List of LDAP servers
%{ldap_uidattr, "uid"}. % LDAP attribute that holds user ID
%{ldap_base, "dc=example,dc=com"}. % Search base of LDAP directory
%{ldap_rootdn, "dc=example,dc=com"}. % LDAP manager
%{ldap_password, "******"}. % Password to LDAP manager

% For authentication via external script use the following:
%{auth_method, external}.
%{extauth_program, "/path/to/authentication/script"}.

% For authentication via ODBC use the following:
%{auth_method, odbc}.
%{odbc_server, "DSN=ejabberd;UID=ejabberd;PWD=ejabberd"}.

% Host name:
{hosts, ["srvis03"]}.

%% Define the maximum number of time a single user is allowed to connect:
{max_user_sessions, 10}.

%% Anonymous login support:
%% auth_method: anonymous
%% anonymous_protocol: sasl_anon|login_anon|both
%% allow_multiple_connections: true|false
%%{host_config, "public.example.org", [{auth_method, anonymous},

Can anyone help me figure out what is preventing me from connecting from the internet?
