This problem may be specific to IPsec traffic (ISPs often > discriminate against traffic with protocols other than TCP/UDP). This is my company network schema: sap server---milano-network==mimosa-+-internet-+-pleiadi==venezia-network--sap client I'm able to connect to a sap server connected to the milano network from a sapgui client connected to the venezia network. No problem. If packet loss is a problem it should be also a problem with this tunnel. Am I wrong?
