Hi, Your example below shows an compressed connection. That means that the data transferred on the wire are less than the data received by the tun device. The ten-fold value is interesting, though you may want to try without compression to figure whether there is an issue or not. > Terminal log: > =============================================================================== > root at 01:~# occtl show user tester4_55 && ifconfig vpns0 && occtl disconnect user tester4_55 > ID: 20927 > Username: tester4_55 Groupname: (none) > State: connected > Device: vpns0 MTU: 1342 > Remote IP: 11.22.33.44 Location: > Local Device IP: 10.140.0.2 > IPv4: 192.168.1.237 P-t-P IPv4: 192.168.1.1 > User-Agent: Cisco AnyConnect VPN Agent for Apple iPhone 4.6.00122 / iPhone1 > RX: 245575 (245.6 KB) TX: 17672025 (17.7 MB) > Average bandwidth RX: 2.2 KB/sec TX: 159.2 KB/sec > DPD: 90 KeepAlive: 32400 > Hostname: iPhone > Connected at: 2018-02-24 23:34 ( 1m:51s) > Session: TZT+MM > TLS ciphersuite: (TLS1.2)-(ECDHE-RSA-SECP521R1)-(AES-128-GCM) > DTLS cipher: (DTLS0.9)-(RSA)-(AES-128-CBC)-(SHA1) > CSTP compression: lzs DTLS compression: lzs > > DNS: 8.8.8.8 > 8.8.4.4 > Routes: defaultroute > Restricted to routes: False > > vpns0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 > inet addr:192.168.1.1 P-t-P:192.168.1.237 Mask:255.255.255.255 > UP POINTOPOINT RUNNING MTU:1342 Metric:1 > RX packets:4217 errors:0 dropped:0 overruns:0 frame:0 > TX packets:13238 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:500 > RX bytes:245575 (245.5 KB) TX bytes:17672025 (17.6 MB) > regards, Nikos
