I have a guest network which works fine all the time. Recently the I have some visitors who have their own VPN sotftware (Tsystems-NA) and never worked.
Long story short:
Many other company's VPN software works. Even the Deutsche Telekom users who have the same vpn software (different version) from Tsystems
I have ASG220 with 9.315-2, the rules
1 I used Masq before Network --Masq--WAN, also tried network-SNAT--Wan.
2 Firewall rules: network--any--internet, also I tried network--any--wan
3 No content filter on this network.
Don't know why. Should I put another firewall rule like Any--any--network?
Thanks,
