(ASCEND) NAT and ELF
hi,
have anybody run NAT and Entry Level Firewall together ???
my config:
P50: - softrel.51Ap9
- Ethernet->NAT->NAT->NAT-routing=yes
- Ethernet->NAT->NAT->LAN=Single IP addr.
- Ethernet->NAT->NAT->Static Mappings->01 Telnet to 10.1.3.30
02 SMTP to 10.1.3.10
...
- Configure->My Addr=10.1.3.30/24 (private)
- Ethernet->Mod Config->Ether Options->2nd IP Addr=193.96.0.129/27 (public)
- Ethernet->Connections->ISP->Session Option->Data Filter=101
- Ethernet->Firewall->301 ELF-Config
ELF: - only in-comming SMPT traffic to 193.96.0.128/27
- only in-comming Telnet traffic to 193.96.0.128/27
- only out-going SMTP,DNS,WWW for 193.96.0.128/27
Without ELF (Ethernet->Connections->ISP->Session Option->Data Filter=0)
i have no problems, NAT works and all local clients have internet access.
But with enabled Data Filter local clients can only access to internet
while open isdn-line. A local client can't open the isdn-line ?!?!
If the line open from outsite or manuel, local client have access!
It's looks like a Call Filter, but there isn't it.
Have anybody some ideas??
Ciao
Frank
