i’m trying to set up our Shoretel voicemail server to be accessible from iPhones. they recommend using a reverse proxy for this. i have tried to set up just a straight NAT for the server, and while i’m able to log in via a web browser, i can’t get the iPhone app to authenticate. my guess is that the reverse proxy isn’t just a recommendation, but a requirement because the Apache configuration they give as an example shows it redirecting pathnames to ports, instead of simply routing port to port. (hopefully that makes sense.)
in other words, the authentication path is /authenticate/ and it’s routed to port 80; the CAS path is /cas/ and it’s routed to port 5447, and the director path (for the actual VM UI) is /director2/ and it’s routed to port 5449. my hope was that if i used NAT, the app would just use the ports and it would work (it doesn’t), but i suspect it’s actually trying to use the pathnames instead. of course, the manuals are completely opaque on this topic, and give no alternative configuration to an Apache reverse proxy, so i’m stabbing around trying to figure out why it works for a web browser but not the mobile app.
anyway, below is the Apache configuration they recommend using. i would appreciate if someone could tell me if it’s possible to translate this into a RouterOS configuration (ideally using WinBox, as i am not skilled in the command line config of MikroTik), and if so, how i would do it, so i can use our MT for the reverse proxy. i know next to nothing about Apache configuration and i really have little interest in learning it and setting up a server simply for this purpose.
also, at this time i’m not interested in the SSL part. at some point i will likely implement this as well but for now i’m just trying to get this working to see if it’s worth the expense of licenses for mobile access.
G.2 Example Reverse Proxy Configuration for Apache 2.2
The following script example illustrates how to configure the reverse proxy on port 5500
for connection to the HQ server at 10.0.0.1
Step 1. Modify httpd.conf to specify proxy port to be used for HTTP+SSL:
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
#
Listen 5500
Step 2. Verify in httpd.conf that the following modules are enabled (uncommented):
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule rewrite_module modules/mod_rewrite.so
LoadModule ssl_module modules/mod_ssl.so
Step 3. Edit conf\extra\ httpd-vhosts.conf:
#
# Use name-based virtual hosting.
#
NameVirtualHost *:5500
<VirtualHost *:5500>
# necessary for rewriting
RewriteEngine on
# uncomment the logging for problem trace only
# RewriteLog "logs/ciproxy.localhost-rewrite.log"
# RewriteLogLevel 3
# NOTE the rewrite rules have a proxy redirect
RewriteRule ^/theme/(.+)$ /director2/theme/$1 [P]
RewriteRule ^/yui_2.7.0/(.+)$ /director2/yui_2.7.0/$1 [P]
RewriteRule ^/js/(.+)$ /director2/js/$1 [P]
ProxyPass /authenticate/ http://10.0.0.1/
ProxyPassReverse /authenticate/ http://10.0.0.1/

# Server Certificate:
# Point SSLCertificateFile at a PEM encoded certificate. If
# the certificate is encrypted, then you will be prompted for a
# pass phrase. Note that a kill -HUP will prompt again. Keep
# in mind that if you have both an RSA and a DSA certificate you

#SSLCertificateKeyFile "conf/ssl.key/server-dsa.key"

# Server Certificate Chain:
# Point SSLCertificateChainFile at a file containing the
# concatenation of PEM encoded CA certificates which form the
# certificate chain for the server certificate. Alternatively
# the referenced file can be the same as SSLCertificateFile
# when the CA certificates are directly appended to the server
# certificate for convenience.

# Certificate Authority (CA):
# Set the CA certificate verification path where to find CA
# certificates for client authentication or alternatively one
# huge file containing all of them (file must be PEM encoded)
# Note: Inside SSLCACertificatePath you need hash symlinks
# to point to the certificate files. Use the provided
# Makefile to update the hash symlinks after changes.

#SSLCACertificateFile "conf/ssl.crt/ca-bundle.crt"
# Certificate Revocation Lists (CRL):

# authentication or alternatively one huge file containing all
# of them (file must be PEM encoded)
# Note: Inside SSLCARevocationPath you need hash symlinks
# to point to the certificate files. Use the provided
# Makefile to update the hash symlinks after changes.

# number which specifies how deeply to verify the certificate
# issuer chain before deciding the certificate is not valid.

# Access Control:
# With SSLRequire you can do per-directory access control based
# on arbitrary complex boolean expressions containing server
# variable checks and other lookup directives. The syntax is a
# mixture between C and Perl. See the mod_ssl documentation
# for more details.

# SSL Engine Options:
# Set various options for the SSL engine.
# o FakeBasicAuth:
# Translate the client X.509 into a Basic Authorisation. This means that
# the standard Auth/DBMAuth methods can be used for access control. The
# user name is the `one line' version of the client's X.509 certificate.
# Note that no password is obtained from the user. Every entry in the user
# file needs this password: `xxj31ZMTZzkVA'.
# o ExportCertData:
# This exports two additional environment variables: SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
# server (always existing) and the client (only existing when client
# authentication is used). This can be used to import the certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related `SSL_*' environment variables.
# Per default this exportation is switched off for performance reasons,
# because the extraction step is an expensive operation and is usually
# useless for serving static content. So one usually enables the
# exportation for CGI and SSI requests only.
# o StrictRequire:
# This denies access when "SSLRequireSSL" or "SSLRequire" applied even
# under a "Satisfy any" situation, i.e. when it applies access is denied
# and no other module can change it.
# o OptRenegotiate:
# This enables optimized SSL connection renegotiation handling when SSL
# directives are used in per-directory context.

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant shutdown
# approach is that mod_ssl sends the close notify alert but doesn't wait for
# the close notify alert from client. When you need a different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is closed, i.e. no
# SSL close notify alert is send or allowed to received. This violates
# the SSL/TLS standard but is needed for some brain-dead browsers. Use
# this when you receive I/O errors because of the standard approach where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection is closed, i.e. a
# SSL close notify alert is send and mod_ssl waits for the close notify
# alert of the client. This is 100% SSL/TLS standard compliant, but in
# practice often causes hanging connections with brain-dead browsers. Use
# this only for browsers where you know that their SSL implementation
# works correctly.
# Notice: Most problems of broken clients are also related to the HTTP
# keep-alive facility, so you usually additionally want to disable
# keep-alive for those clients, too. Use variable "nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to workaround
# their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
# "force-response-1.0" for this.
