Hi,
I have one specific routing situation that I still can't handle, so I am
asking for some help.
I have Linux server, one eth interface and 2 DSL links. One DSL is VPN
link to another site's Web Intranet application. VPN link itself is
realised via DSL line and CISCO router. Local users can work with that
application. Another DSL is Internet gateway for local users, and
incomming channel for accessing server from outside (there is Siemens
DSL router).
I want to provide that external remote users can connect to that server
from Internet and use that Intranet application via another DSL and VPN
channel.
Route table:
# route -n

...93.64/26 is LAN,
...93.65 is VPN gateway to Intranet Web server on another site,
...93.122 is Internet gateway,
...30.9 is Intranet Web server with The Application on remote site.
Local users can go to Internet and on Intranet app on remote site, and
that works fine. I need rules that Internet users comming from public IP
using http://mysite.dyndns.biz:myport through ...93.122 can go to
http://192.168.30.9:80. I succesfully set forwarding on DSL router so
incomming packets comes to server on port 'myport' (I can't
reroute/rewrite packets on DSL router itself).
I tried with one PREROUTING rule, but I can't rewrite both source and
destination address, so obviusly I need two rules?
Thank anyone for any help,
GI
