[OpenSBC] openbc as proxy behind NAT-Router

[meute <ope...@op...>]

Hi,

this is my network-scenario:


(192.168.209.156)Xlite 3.0
|
|
|
(192.168.209.1)
RouterOS(redirect all traffic from 209.156 dst-port 5060 and 30000-30019 to=
 10.111.0.200)
(10.0.10.100)
|
|
|
(10.0.10.254)
RouterOS
(10.111.0.2)
|
|------(10.111.0.200)FreeBSD opensbc
|
|
|
(10.111.0.1)
Lancom DSL 10 doing NAT (UDP: 5060 and 30000-30019 to 10.111.0.200)
(external dynamic ip)
|
|
Internet

My Configuration of opensbs:

OpenSBC General Parameters: no changes made
Trusted Domains: Accept All Calls
Privacy (RFC 3325): no changes made
Local Domain Accounts: Accept All Registration
B2BUA Routes: No Entries
Relay Routes: [sip:*] sip:91....@si... | 91.17.31.56 is the pre=
sent external ip adress
Internal DNS Mapping: No Entries
Upper Registration Routes: [sip:*@1und1.de] sip:sip.1und1.de:5060
Media Server: no changes made

X-Lite has the following error:
Registration error: 403 - No RFC1918-IP's allowed

Xlite Firewall Traversal Config:
Discover global address: yes
Use specified server: stun.1und1.de
Enable ICE: yes

I think opensbc don=B4t rewrite the ip address of the request to the extern=
al ip and i don=B4t know how to get this working. might be small entry?

thanks,
meute
