| Hi!
I need to access my office network with Nortel Networks Contivity VPN
Client (V05_01.030) and the US Robotics Router USR139108A, but the
client is not able to establish the connection. I really don't know
too much about VPN, so any help would be appreciated.
I tried to open port 1723 TCP in the router firewall and disable
keepalives in the VPN Client but the connection is still impossible.
By the VPN Client side I can read this kind of log:
"Connection initiated to name.domain [xxx.xxx.xxx.xxx] using Diffie-
Hellman group 8."
"Isakmpd | E | Unable to complete encryption handshake with remote
side. Encryption Mismatch."
"Connection initiated to name.domain [xxx.xxx.xxx.xxx] using Diffie-
Hellman group 2."
I also get this error by the router side many times: "kernel: net/ipv4/
netfilter/./broadcom/ip_nat_ipsec.c:ipsec_nat_help Out of table
entries ".
Probably this stuff isn't enough to understand my problem but I hope
someone can show me what to do.
Thanks,
Daniel
